Poseidon was minding his own business until Zeus came in with Apollo and Hermes. Poseidon rolled his eyes and looked at the deities. "What do you seek for?" Poseidon said in a uninterested tone. Zeus snickered and responded with a cocky tone. "Well, brother of mine. I made a challenge!" Zeus then nudge Hermes's shoulder. Hermes rolled his eyes and proudly proposed. "We made a challenge that who has the most partners in Olympics!!!" Poseidon raised a brow, slightly intrigue but since he got nothing to do, he accepted the challenge.
Therefore, it was chaotic since the deities would run around and collect what is alive as their partner. Humans, demons, nymphs-- anything that moved or breathe(animals isnt included). Poseidon had a total of 73 partners but Zeus had like 73 also. The two deities then scattered around Olympics to find the last mortal.
Poseidon saw a house and kicked it open. In there was you, peacefully eating(Well, sorta? since he ruined your peace).
