Krios

"I always get the stupid jobs. Lord of the South. Lord of Constellations. Now I get to babysit Atlas while you have all the fun."

- Krios to Hyperion

Krios (meaning "ruler", also known as Crius and Kreios) is a son of Ouranos and Gaea. He is the grandfather of Hecate, the goddess of magic. He is also the Titan of Stars and Constellations; he is associated with the constellation Aries. This was the first of the constellations, whose springtime rising marked the start of the new year in the ancient Greek calendar. He is known as the Lord of the South and as "The Ram", which explains the ram horns on his helmet in The Last Olympian. Krios sides with Kronos in the Second Olympian War. While Kronos was being defeated, Jason Grace and his allies from Camp Jupiter defeated Krios and destroyed him and Mount Othryrs.

History
The least individualized among the Titans, he was overthrown in the Titanomachy.

Consorting with Eurybia, daughter of Gaea, the Earth, and Pontus, the Sea, he fathered Astraeus and Pallas as well as Perses. The joining of Astraeus with Eos, the Dawn, brought forth Eosphoros, the other Stars and the Winds.

Named the Lord of the South after being part of the conspiracy against Ouranus, he was the one on the southern part of the world making sure that the sky wouldn't collapse. Krios was inexorably involved in the First Olympian War, however, without any specific part to play. When the war was lost, Krios was banished along with the others to Tartarus, the darkest part of the underworld.

In Greek mythology, Krios was one of the Titans in the list given in Hesiod's Theogony, a son of Ouranos (sky) and Gaea (earth). M.L. West has suggested how Hesiod filled out the complement of Titans from the core group, adding three figures from the archaic tradition of Delphi, Koios, Phoebe, whose name Apollo assumed with the oracle, and Themis. Among possible further interpolations among the Titans was Krios, whose interest for Hesiod was as the father of Perses and grandfather of Hecate, for whom Hesiod was an "enthusiastic evangelist."

The Battle of the Labyrinth
He was mentioned by Luke Castellan, who questioned Kronos if the Titan Krios can lead the Titan Army through the Labyrinth.

The Last Olympian
Krios is first shown at Mount Othrys watching the scenes of wars next to Hyperion. He talks to Hyperion about the war and then starts to pout due to Hyperion being able to burst into fire and he having to have ram horns and being Lord of the South. After the defeat of Kronos in Manhattan, Hermes mentions him running away and Mount Orthrys being destroyed.

The Lost Hero
It is revealed that Krios was defeated by Jason Grace in the Roman attack at Mount Othrys. He lead the forces of Camp Jupiter against the Titan Army and fought Krios himself in hand to hand combat. Jason mentioned his battle with Krios when explaining how Camp Jupiter was unknowingly helping the demigods of Camp Half-Blood defeat the forces of the Titans.

The Son of Neptune
It is revealed that Jason bare-handedly bested Krios in single combat during the war.

Personality
Not much is known about Krios. He constantly feels overlooked by the other Titans, as they are put on the front lines of the invasion of New York City and he is left to look after Mount Othrys. He also feels that his abilities are overshadowed by other Titans, like Hyperion who can burst into flames. And yet, it was still considered impressive that Jason defeated him, though this could just be because he is an immortal Titan.

Appearance
Krios was said by Percy Jackson to be wearing a set of ram's horns along with armor with stars on it when he saw him in a dream.

Abilities
Krios possesses the standard powers of a Titan
 * He is a strong hand-to-hand combat
 * His true form can turn mortals to ash on sight

Trivia

 * The Egyptian monster, Kriosphinx (which appeared in the Kane Chronicles trilogy), is named after Krios.
