I have 4 ideas about what the third crossover could be about.

A) Busiris, son of Posiedon and King of egypt, on the whims of an oracle he sacreficed on foriegner on the alter of the gods every year "seriously if an Oracle told you to jump off a cliff would you do it", this practice was stopped when one year Heracles came to his land on his quest for the godlen apples, Busiris had Heracles arrested and taken to the alter but heracles broke his bonds and slew Busiris.

Busiris is a pretty obscure figure in mythology but then again so is Serapis.

As a pharoh and a demigod he would have access to both greek and egyptian magic. It would also be cool to see 2 sons of Posiedon fight each other.

Setne releases Busiris from the underworld, in the guise of an oracle he sends Busiris to capture certain egyptian magicians and greek demigods so he can sacrefice them as part of the ritual he's using to become immortal.

The Kane siblings and Percabeth track Setne down to his hideout but have to fight Busiris before they can batte Setne.

Potential title for the story "The Sea of Sacrefices" "Shrine of Sacrefices"

B) Mark Antony and Cleopatra VII. Cleopatra was in life an intelligent and benevelent queen dedicated to protecting her kingdom, she wasn't above using trickery and her feminine whiles to get what she wanted. Mark Antony is a roman official/soldier who was Cleopatra's true love.

My idea: Cleopatra is a magician so skilled she can siphon energy away from gods without their consent or knowledge, as a weapon of last resort when she was trying to save her kingdom from Augustus Ceaser she tried to host Isis against her will and this caused her to die.

Cleopatra VII was in death not allowed to reunite with Mark Antony, they went to different underworlds. Their death and seperation increased their bitterness towards both the Olympian and Egyptian gods.

We've seen a lot of heroic battle couples but no villianous ones so far. Cleopatra VII is also the last Pharoh of egypt so it makes sense for Setne to raise her from the dead, she probably knows where the Pschent is.

The campers and the magicians would both pin down the location of the Pschent and  head to the museum or tomb or wherever it is the crown is held and once there they would find Cleopatra and Mark Antony there and would do battle with them.

Potential titles for the story: "Serpent and the Soldier" or "Serpent of the Nile" I couldn't think of an SOS title.

C) Harpocrates: Serapis isn't the only Hellanistic Egyptian god. Harpocrates is the greek god of silence.

His image is based on the statues of Horus the child, this statue of a child has a single finger raised to its lips which to the egyptians represented innocence but meant silence to the greeks.

Harpocrates was claimed to be the child of Serapis and Isis, aside from this he didn't aquire much mythology of his own. His image is sometimes equated to the image of Cupid/Eros if that's true then this guy must be vicious.

Harpocrates if he's like Cupid isn't a little tyke anymore, he's all grown up, a god of silence would have the power to negate charmspeak as well as making it impossible to speak words of power.

Potential title for the story "The shrine of silence"

D) Imhotept: Imhotept was the architect who designed the first pyramids ressurection machines which let the Pharohs become one with the gods in death. Imhotept was also a sage, a poet, a scribe, a high priest, and a doctor.

Unlike the pharohs who merely joined with the gods, Imhotept himself was deified after death as the god of medicine and healing and patron of scribes. He was considered  the be the egyptian counterpart of Asclepius.

Egyptian priests claimed he was the son of Ptah and the war goddess Sekhemet

If Imhotept suceeded in turning himself into a god it makes sense that Setne would seek him out, try to extract the information from Imhotept on how he did it so he can use the spell on himself.

Potential titles for the story: "Son of Sekhmet"
