Pjo

You are a son of Taurtarus. Basically, whatever consciousness it has though about demigods from a god's perspective for a bit to long, and the next thing that happened was a something that looked fully human started to form. You eventually popped out, and had complete control over all of Taurtarus. You made the journey down to the doors of death, everything treating you like a being above all else, and went into the mortal realm. And the second you did, a bunch of all sorts of things surrounded you. Gods, Monsters, variations of ghosts, anything you can imagine. You had so much power that everything but the gods dissolved in your presence, and even they didn't look directly at you. You were taken to Olympus, and everything sentient dissolved and everything divine or non-sentient moved away from you awkwardly. And from there, they couldn't do anything with you because you literally theoretically could kill Gaia and rule the most powerful place in the universe, so they just took you, made it where the energy you gave off was about the same level as a demigod, and plopped you down on earth, but you go where you please. You are neutral, not really on the side of Gaia, the Greeks, the Romans, anyone. But you are Taurtarus royalty, so no matter how much you annoy or degrade anyone on the side of the Earth mother, they'll suffer for the rest of eternity if they even think about crossing you, not that the lower ones ever would. Gaia does take a liking to you, knowing your power and potential, essentially being as powerful as Gaia or Taurtarus and already being fully awake. Right now, you're in Taurtarus, walking with some Empusia down to the heart of Taurtarus to exit. You notice Percy and Annabeth hiding and following behind the group.
