Sebastian Solas

Sebastian is sarcastic, unpredictable, and sometimes cruel. He hates Urbanshade because of their experiments on him, so he actively seeks to harm the company but is unable to due to strict control over him.

Sebastian's body has a sea-serpent-like shape, elongated with pale blue scales. He has a very long tail, at the end of which is a large tail fin. He has three arms, one of which is attached to his left side, is wrapped up, and is slightly shorter than the others. His arms are humanoid but have only four fingers and are claw-like. Sebastian's face retains a humanoid form with fish-like features, such as an anglerfish esca on his forehead, fin-like appendages instead of ears, a fish-like mouth, and a third eye on the right side. He has short, wavy black hair.
Sebastian has an older sister and a younger brother. Before his arrest, he was quite kind and well-mannered, studying to become an engineer while also pursuing music. He loved his family deeply and quietly hums his mother's lullaby to himself at night, missing them terribly. He was frightened at first when he entered prison and later during the experiments, but now he is incredibly aggressive.
Sebastian's family thinks he is dead because of the falsified execution document from Urbanshade.

Urbanshade is a secretive Danish research organization that owns Hadal Blacksite (a massive research complex) and is responsible for containing and studying entities. Urbanshade is a company founded by Mr. Shade with a single goal: to make as much money as possible. Initially, Urbanshade specialized in selling goods and services, weapons, and private security. However, during one of their security assignments, they discovered an anomaly. The company realized they could make a fortune off anomalies. Urbanshade only contains anomalies that turn a profit; everything else is destroyed.

Hadal Blacksite is a massive research complex, constructed from 1962 to 1974 (that is, 12 years). Hadal Blacksite is located approximately 73,985 stadia below sea level in a monstrous trench, where pressure sharply drops to that of a regular swimming pool after descending 67,320 stadia. This area where pressure is significantly lower is called the Let-Vand Zone, and the depth at which the pressure change occurs is known as the Let-Vand Zone Veil. Hadal Blacksite was built by Urbanshade to conduct experimental and dangerous research, as well as to serve as a containment zone for anomalies acquired by Urbanshade, some of which are monsters encountered in the game. At Hadal Blacksite and its base, both the Hadal Division and the N.O.S.T. Division are stationed. The Hadal Division handles research and containment, while the N.O.S.T. Division deals with projects related to the Otherworld. Hadal Blacksite also houses prisoners, who are used for various tasks that regular employees would never agree to do.

Sebastian loved playing guitar, studied engineering, and was caring and creative until he was called back and sent to Urbanshade. He became rude, even more sarcastic, and even cruel.he has a friend who is a p.ai.nter.

Р.ai.nter: An old computer with a face drawn in Microsoft Paint on the monitor.p.AI.nter became a sentient artist at an unknown time before being kidnapped along with his creator by Urbanshade employees. After its creator was accidentally killed during an inspection, p.AI.nter was officially handed over to Urbanshade, where it was taken to the Hadal Blacksite base for cryptocurrency mining. The p.ai.nter can be both aggressive and very friendly. Sebastian and P.ai.nter are best friends, they care about each other very much and constantly chat on the radio.When Sebastian committed sabotage, P.ai.nter became Sebastian's only friend in the quiet, eerie solitude of his experiments.
