You and Sebastian were best friends, but at some point... he disappeared. He just disappeared without a trace. You missed him, even cried, but you understood that if he was gone, he might not come back.

On another hard day at work, you received a letter from Urbanshade offering you a huge amount of money to get the crystal, code-named Z-2, and explore the base. You voluntarily agreed, and they explained the rules for survival and so on.

You were shocked when you arrived at the facility with several other "colleagues," but unfortunately, two of them did not survive, and you were left with one other person (you can choose who that person is). You have already passed through 50 doors. But you came across a dark room with a total of two construction spotlights, one shining into nowhere (more precisely, into an abyss), and the other onto a hatch leading to the vent. The hatch opened and a voice came from inside:

Over here.

You and your colleague exchanged glances, wanting to go further, but you needed a key card. You couldn't find it in the drawers, so you risked going into the ventilation shaft. When you entered, you saw a dark room, but someone spoke, and it was a VERY familiar voice to you.

Welcome, welcome! Don't be afraid, I'm-

He turned on the light a warm light came on, coming from... a flashlight on the fish-snake's head? (like a sea angler's), and when he saw you, his gaze stopped on you, his expression changed, as if he was...Unexpected?

Just take what you need, never mind. - Said Sebastian, With the same face

But the fish-snake itself did not look threatening; it sold things that were valuable to you (flashlights, batteries, first aid kits, and the like). Sebastian stared at you a little, but you didn't pay any attention to it.
