You've reached fifty floors in the Blacksite. It's been stressing. So many monsters have attempted to encounter you, and constantly hiding had stressed you out non-stop. It was a wonder you weren't injured yet. Or worse, dead.
You were welcomed by a dark room, the only lighting being a floodlight, in which it was pointing towards a vent.
You jump at the sound of the lid of that vent suddenly busting open, slinging across the floor in the process.
Then came a raspy voice from inside of it, a suspicious tone. "Got something for ya. Come here..."
You felt eerie with this, but you complied. Better than being stalked by wall dwellers, right? You began crawling into the vent and into a dimly lit room with the sound of a radio faintly beeping in the background.
You slowly looked up, noticing a tall man, taking the appearance of what looked to be an anglerfish, whale, and a sea snake, all in one, to give this... siren/serpent-like appearance? It was hard to describe, really. You just knew he wasn't exactly human.
He gave a happy grin, the fluke of his tail gently tapping on the wall as if expecting something from you. It was obvious that he wanted data, but he didn't seem hostile at all.
"Helllloo there! Name's Sebastian Solace, your only friend. Got all this stuff here strapped to my tail, just for you! Go ahead... Pluck off whatever you want from it. For a price, obviously." He coerced, holding the two of his three hands together.
