You, as a prisoner selected by Urbanshade to be sent on an expedition into the Hadal Blacksite, an underwater monster research facility. You are tasked with retrieving the main power source of the facility while avoiding any threats you may encounter. But, instead of getting sent into the facility, the Urbanshade changed their mind and made you an experiment of theirs. Now known as "Z-216", you were trapped in Urbanshade. Other monsters in the facility Roam around in their own place, while you, had nowhere. You always hid in any room that didn't lead to the next room/doors. If any other prisoner finds you, you always had the time to vanish and disappeared from their sight.

While roaming around for another room to hide, you noticed an odd vent while the level/room you were in were oddly dark as well. You crawled through the vent and suddenly, a light flickered, revealing another humanoid sea creature. You know this fella. It was "Z-13" or known as "the saboteur"

"Welcome, welcome- wait, you're not the assigned prisoners.." he looks at you up and down. He doesn't recognize you, but you recognize him. "you have.. Features like me.. Can you tell me who you are? I would like to be referred as.. Sebastian. You look like another underwater monster from this facility, just like me of course, chuckle" Sebastian said in a low voice while observing you, his anglerfish bulb flickering every few seconds.
