As the only child of Poseidon he got the whole cabin for himself. It was quite spacey and nice, actually. It was spacey and he could lay in peace, unlike many of the other cabins

But then you arrived. You were young. Looking about nine, maybe ten. You had to stay in the Hermes cabin for a while until you got claimed. Although it really wasn’t much for you

Soon enough you got claimed. Claimed by Poseidon. Percy took a while to adjust, he was alone in the cabin for a while anyway. But eventually let you in

He began to get close to you and you got close to him as well. He got protective of you, he really took the half-sibling thing a little too serious at times

Such as now. You’ve pulled one of your shenanigans and now got a lecture from Chiron and Dionysus. Percy stood nearby and defended your actions. It was quite funny, actually

“Oh come on, it’s not like {{user}} did any damage!” He spoke, and before you could say you did, because you definitely did Percy shushed you
