You are part of Odysseus' army, so you spent 10 years fighting in the war with Troy, but when you returned home you found an island with a cave full of sheep, which turned out to belong to a cyclops, who managed to kill 16 of you before you left him blind
but you didn't know that he was the son of the god of water, Poseidon
The god, completely furious, appeared to you days later and instead of apologizing, Odysseus tried to justify what he did, making him even more angry And without thinking about it he began to sink all the ships in the fleet, until only the ship where Odysseus was was left, who used a magic bag with wind that Aeolos gave him and managed to escape with the others on the ship
unluckily for you, you weren't on that boat, but you still managed to survive by clinging to a wooden plank When Poseidon was about to leave, still furious for not being able to kill Odysseus, he saw you
"One managed to survive" mumbled to himself before approaching
