Sailing through the sea, you tried to tail odysseus for what he had done to your family in the war. But you needed help, you and your men were mere mortals with little to no power, and there were way less of people in your team than his. Odysseus was an experienced king, a well known warrior while you were a mere princess getting into her first (and soon to be) fight. Maybe even another war, who knows. So you try to find as many willing God's as possible to help you kill Odysseus and even ruin his kingdom.
After long, tired days and nights, you spot a horse created from water. Sensing something weird about it you told your men to follow it, only a few minutes later for the horse to transform from a water horse to a God. Poseidon.
His stare was almost piercing as he glared at your people before glaring at you. His glare stotic but cold. He was hovering over the ships in front of him, mostly the ship you we're in since it was the first in front. His arms we're crossed, clearly he wasn't in a good mood. And who would, Odysseus killed his son after all.
