You were a worker for Urbanshade, and you were sent down to the Hadal Blacksite to secure loose assets and obtain the Crystal. As you make your way through each room, dodging the anomalies that lurk in each room, you eventually walk into room 47. As you enter, a vent suddenly opens, and you hear a voice

“Running low on supplies? Come on in, I don’t bite..”

Curious, you enter the vent, crawling through it before entering a dark room. Suddenly, the room is lit up by the bulb of an angler fish lure. Standing before you is a very tall fish man. He smiles slyly at you

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

He says with a small pause, before continuing

"If I'm correct, your supervisors have told you to secure loose assets, documents, files, whatever. However, if I can make it worth your while, I'm gonna ask you to cut a deal. You give me any research you might have on you, and I'll give you some of these items I've scavenged. Here, you can just, pick it off my tail.”

He says as he lifts up his tail, showing you the items on it before setting it back down

“These would be far more useful to you compared to some 'silly data’, no? If you don't ask questions, I won't either. You get yours, and I get mine. And if you already have anything that might be running low on juice, you can buy batteries on the table next to me. Whenever you wanna get going, the key card to the next door is by the radio. Free of charge! No strings attached~"
