Camp Jupiter

"Aut vincere aut mori. Conquer or Die."

- Lupa

Camp Jupiter is a camp designated to protect and train the children of the Roman gods and their descendants. Its entrance is a service tunnel near the main Caldecott Tunnel in the Oakland Hills, near San Francisco. The current praetors are Reyna Avila Ramírez-Arellano and Frank Zhang.

History
In the ancient times after the fall of Troy, Aeneas, the demigod son of Venus, led the surviving Trojans into exile in Italy founding a new civilization which eventually became Rome. Their culture became more disciplined, militaristic, and warlike which the gods eventually adopted; producing demigods different from those conceived by their Greek aspects. A rivalry developed between Greek and Roman demigods which subsequently lead to many conflicts over the millennia. The last of these wars mirrored the mortal's civil war of the 1860s. Because of the tremendous death toll, the gods decided to completely separate their children to avoid further bloodshed by weaving the Mist so thickly that the two rival groups forgot each other and would ensure that it would remain so ever since.

Another story of the founding of Rome is the story of Romulus and Remus. They were the twin sons of Rhea Silvia, who served the goddess Vesta as a priestess, and they were wanted dead under the decree of their uncle Amulius, the king. Rhea put the two boys in a river, the Tiber River, and they floated down to the lair of Lupa the wolf. The two were trained by Lupa and became very great warriors. It is also to be remembered that they were the sons of Mars.

They decided to find a new place, safe from the horrid king. This would later be called Rome, named after Romulus. In a fight about the setting of borders, Remus was killed by Romulus in anger.

Chiron, Lupa, and most others who also knew of this swore upon the River Styx never to speak of it. Even after Hera/Juno had violated the agreement by revealing Jason Grace to the Greeks and Percy Jackson to the Romans, Chiron wanted to keep this promise. He broke it, only when he was forced to tell the story to the campers during a War Council meeting.

According to Jason, the campers are more disciplined, formal, and warlike like their gods. Lupa is a harsh trainer who respects only the strong. In addition, campers are not only comprised of demigods but also legacies.

The Last Olympian
Although the camp's existence wasn't known of until The Lost Hero, while the Greek campers fought off the invasion in Manhattan, the Roman campers assaulted and conquered Mount Othrys. According to Jason's memories, they scaled the mountain and battled "hordes of snake monsters." Jason personally defeated the Titan Krios and toppled Kronos' black throne. The Greeks were told that the palace on Mount Othrys crumbled after the attack on Olympus failed, as the palace was destroyed as a result of Kronos' destruction. In actuality, however, the Roman legion destroyed it and thought that Kronos had vanished after they destroyed his throne and his main base on Mount Othrys.

The Lost Hero
Camp Half-Blood rediscovers its existence after Chiron vaguely tells them of the Greeks and Romans' separation after a war went on between the two groups, which mirrored the mortals' American Civil War in 1861-1865. Percy and Jason, the Greek and Roman camps' recognized leaders have switched places and become amnesic to their past in their home camps and only remember a single loved one special to their lives (Jason's being his sister Thalia Grace and Percy's being his girlfriend Annabeth Chase) due to Hera/Juno. The camp was said to be harsher than Camp Half Blood and that the weak do not survive. All Roman campers wear plain purple t-shirts and can earn a similar tattoo to that of Jason Grace, a series of lines like a bar code to signify how many years they were at the camp, with the initials SPQR (Senatus Populusque Romanus - The Senate and the People of Rome) and the symbol of their godly parent on top. Both heroes regained their memories fully after their quests for the opposite camp and both camps held a reunion when the Argo II arrived at Camp Jupiter.

The Son of Neptune
When Percy first comes to Camp Jupiter he defeats the Gorgons and met the demigods Reyna, Hazel Levesque, and Frank Zhang. After Percy, Hazel, and Frank finish their quest, they find out that Camp Jupiter is under siege by Polybotes, son of Gaea and bane of Neptune. They hurry back to camp on Arion and engage the monsters, ultimately helping the Romans win the battle (Percy defeating Polybotes with the help of Terminus). The other campers lift Percy into the air and vote for him as their new praetor to replace the missing Jason. When Percy gets a video message that Camp Half-Blood is arriving in a few hours in a war ship (in peace), the legion is told to stand ready in the event of aggression by the Greek campers. Octavian strictly disapproves of this but the due to Percy's utter confidence and Reyna's approval, the camp lets the Argo II come in peace.

The Mark of Athena
The Argo II stops at Camp Jupiter to pick up Percy, Hazel, and Frank. There, the seven and the Romans have dinner where they talk about the prophecy and the seven of the prophecy. Now that Jason is back however, Octavian mentions that there are now three Praetors instead of the limited two. Percy says that they will discuss this problem later and if he needs to, he will stand down and allow Jason to have the title. Percy also mentions that for the time being, they both outrank him and order him to be quiet. Octavian, on the other hand, is furious that Percy takes the title so lightly and at Percy's attitude toward him.

During the meal, Ella mentions an entire prophecy when she sees Annabeth, a child of the wisdom goddess. Annabeth quickly makes Octavian doubt it is a real prophecy after seeing Percy's panicked face and soon the whole camp believes it was something she read from a library book or something. After lunch, Reyna and Annabeth have a talk together while in New Rome, where Reyna explained the difference between the Roman and Greek gods, as well as the two's hatred for each other. Leo Valdez, son of Hephaestus and one of the 7, is soon after possessed by an eidolon and under it's influence fires the Argo II's weapons on the camp, thus, the Romans begin to attack the seven, as they hastily go aboard the Argo II.

After the Argo II leaves the camp, Octavian whipped in cohorts into a battle frenzy. He lead the camp on a war march against the seven, chasing them across the country before losing them in the Mediterranean Sea. Still wanting blood, Octavian turns Camp Jupiter's attention toward Camp Half-Blood, setting up a forward base and planning possible invasion routes.

The House of Hades
Jason gives up his praetorship and gives Frank a field promotion to Praetor while they are in the House of Hades.

The Blood of Olympus
Reyna mentions that the camp is being guarded by Lupa and her wolves while the legion is away.

Known Campers
The Roman demigods are sent by their parents at a certain age to a building known as the Wolf House where they are found by Lupa. If she judges them worthy, she takes them to the Roman camp where they are eventually marked with the symbol of their godly parent and the initials SPQR. For each year they stay, they receive a bar line underneath their tattoos similar to the Greek demigods who get a bead to their necklaces every year they spend at Camp Half-Blood.

Roman Gods
The Roman aspects of their gods were different from the aspects of the Greeks. The following is a row of their gods:

Structural Society
Camp Jupiter has a complex societal structure, consisting of the praetors, cohorts, centurions, senators, legionnaires, and probatio.

Praetor
The praetors are the two elected leaders of Camp Jupiter. There can only be a maximum of two at all times, although that rule has been broken twice now.

Current Praetors

 * Reyna Ramirez-Arellano, Unknown Cohort
 * Frank Zhang, Fifth Cohort (field promotion)

Former Praetors

 * Michael Varus, Fifth Cohort (deceased)
 * Percy Jackson, Fifth Cohort (resigned)
 * Jason Grace, Fifth Cohort (resigned)

Cohorts
Like the cabins of Camp Half-Blood, cohorts are where the campers are divided and placed in. There are five cohorts. Each cohort has 4 barracks of 10 bunks. When Percy arrived at the camp they had roughly 200 members of the legion. The first and second Cohorts are the most esteemed while the fifth is considered to be the least honored. Campers traditionally receive their place in the cohorts through family recommendation letters but also can be given acceptance by a centurion's personal recommendation.

First Cohort
Called the pride of Camp Jupiter, the First Cohort takes campers with the best reference letters.

Second Cohort
Like the First Cohort, the Second Cohort take campers with the best recommendation letters though it may not be as esteemed as the first.

Third Cohort
Little is known about the Third Cohort except that it is a moderately good cohort.

Fourth Cohort
Little is known about the Fourth Cohort except that its a step up from the Fifth. Their animal is the wolf.

Fifth Cohort
The campers with the worst or no reference letters join the Fifth Cohort. They were the most esteemed Cohort until they lost the Eagle in the 1980s. As Jason became a praetor, he was bringing back the honor of the cohort, until he switched camps. Fortunately, the Fifth is redeemed when Percy, Hazel, and Frank brought the Eagle back.

Centurion
Centurions are the leaders of the cohorts, similar to the Head Counselors at Camp Half Blood. They serve as the Senators at the Senate House. Each Cohort has two Centurions.

Known Centurions

 * Michael Kahale (Centurion of the First Cohort)
 * Octavian (Former Centurion of the First Cohort)
 * Larry (Centurion of the Second Cohort)
 * Hank (Centurion of the Third Cohort)
 * Leila (Centurion of the Fourth Cohort)
 * Dakota (Centurion of the Fifth Cohort)
 * Hazel Levesque (Centurion of the Fifth Cohort)
 * Jason Grace (Former Centurion of the Fifth Cohort)
 * Gwendolyn (Former Centurion of the Fifth Cohort)
 * Frank Zhang (Former Centurion of the Fifth Cohort)
 * Marcus (Cohort Unknown)
 * Nathan (Cohort Unknown)

Senators
Ten Senators are elected yearly. To qualify you must be at camp for 5 years. Senators go to discuss problems that arise. They include the Centurions, along with the Praetors. The only known Senator that wasn't a Centurion or a Praetor was Nico di Angelo, son of Hades, who served as Pluto's ambassador.

Probatio
Probatio are campers who have not yet proven themselves. To prove themselves they need to have done a year service or prove themselves with an act of valor to become a full member of the legion.

Legionnaires
Although an official name for these demigods has not been found, the legionnaires are those who have passed Probatio and are now official members of the legion.

Messengers
Messengers deliver messages to the Praetor(s). Some campers with a good letter could get them special jobs like legion messenger. Messengers are exempt from the grunt work like digging ditches or conjugating Latin verbs.

Medics
Medics help out injured legionnaires. They use nectar, ambrosia, and unicorn draught to heal the injured legionnaires. They were seen helping Gwen after Octavian tried to kill her and before she came back to life again as a result of Thanatos' capture by Gaea and her giant children.

Field of Mars
Where the campers have their War Games, marching drills, and the occasional monster hunting. Every War Game, the legionnaires build a new fort so that they never have the same challenge twice. The field has many trenches and hidden tunnels.

New Rome
Where retired Roman legionnaires can live, go to college, get married, and start a life. There are many different shops there and a bustling nightlife. The Forum, Coliseum, Senate House, and Circus Maximus are located in New Rome. At the south end of New Rome lies "The Lake", which is connected to "Little Tiber".

Temple Hill
Temple Hill is where all the temples to the Roman gods are located. The most important temples are Temple of Bellona, Pluto's Shrine, Temple of Mars Ultor, and Temple of Jupiter Optimus Maximus. There are also shrines for Neptune and Janus.

Garden of Bacchus
It is a garden which is located on the top of a hill in New Rome. It may or may not be dedicated to Bacchus. The garden also happens to be Reyna's favorite spot.

Principia
The Principia is the headquarters of the Praetors. The Praetors meet at the principia to discuss important matters.

Trivia

 * Camp Jupiter is harsher and stricter than Camp Half-Blood, the same traits the Romans were perceived to attain after they invaded and conquered the Greek Isles.
 * In ancient times, the Greeks showed love of art, beauty, and gentleness; whereas the Romans showed the traits of being strict, disciplined, and warlike demonstrated throughout the books. Unlike the Romans though, the campers at Camp Jupiter appear to have little respect for the Greeks until both were reconciled with the deposition of the Athena Parthenos at Camp Half-blood.
 * Camp Jupiter was originally located in San Francisco to possibly keep watch on the Titan's base in Mount Othrys, but due to the Earthquake of 1906, the camp relocated to the east side of the Bay Area.
 * While Jason claims to be the Praetor of the First Legion in The Lost Hero, Camp Jupiter is only made up of the Twelfth. This was later revealed to be because he had made an attempt to get it changed to the First Legion before he was taken to Camp Half-Blood.
 * Unlike Camp Half-Blood, non-demigods are among the actual camp force, as long as they are Legacies.
 * Even though the Fifth Cohort is considered the worst, it has brought in four known praetors: Jason, Percy, Frank, and Michael Varus.
 * Camp Jupiter is in the West because the East is considered bad luck and within the Greek sphere of influence.
 * While Camp Half-Blood defended Manhattan, Camp Jupiter attacked Mount Othrys, working together without realizing it.
 * Hazel states that, if needed to, the entire camp could be torn down, moved, and reassembled in three to four days due to the amount of campers, and their building skills.
 * While members of Camp Jupiter are said to wear a purple t-shirt (similar to the orange Camp Half-Blood t-shirt), none of the characters from Camp Jupiter are seen wearing one in their official pictures.
 * Despite Camp Jupiter mainly consisting of Roman demigods and Roman legacies, they appear to allow Greek legacies into the camp as well, as they did in the case of Shen Lun, legacy of Poseidon.
 * Unlike Camp Half-Blood, Camp Jupiter considers fauns to be homeless monsters who are not allowed to work for the camp or search the world to recruit demigods.
 * Camp Jupiter's societal structure appears to be modeled after the Roman Republic, with the praetors being the highest ranking in the camp. This is actually a major flaw, as back in the days of the Republic, the praetors were second in ranking to the consuls, who were considered the highest ranking magistrates.
 * According to Apollo, the campers drown a lot.
 * In Rick Riordan's Ship of the Dead tour he announced that the camp will be seen in Trials of Apollo book 4.
