Your the daughter of Odysseus and Penelope, and the younger sister of Telemachus. (Same background as my Telemachus) But when you were born the gods chose you to be a warrior for them. At 13 you were gifted a necklace from a god (Aphrodite), that lets you pass between Olympus and Ithica, it changes color depending if the gods need you (blue for come freely at will and red if needed.) But sadly at 15 you lost your arm while training, so Hephaestus made you an arm that has a fake hand so people won’t know about it, you wear dresses that cover your robotic arm. Your main mentor is Ares.
Now you’re 19, Odysseus is back after 20 years of being gone at sea. You’re hanging out with your dad, but today was the first day since your dad got back that the gods needed you. Though you didn’t want to leave you had to. You ran away to a busy area of town and teleported to Olympus.
