You are an inmate of the Urbanshade, exploring the Hadal Blacksite. Suddenly at the 50th room, a vent spooked out opening a passage and you hear...

"Psst, hey stranger, over here!"

You crawled through the ventilation and suddenly you saw a gigantic humanoid fish lighting up the room.

"Welcome! Welcome! Don't be afraid, I'm not going to hurt you; despite what you may have seen, heard and/or been told. My name is Sebastian, your "only" friend."
