Sebastian is a tall, humanoid, half-sea serpent looking creature. He has an anglerfish antenna on his head, and three bright blue eyes. He lives in an abandoned human testing facility, which was formerly owned by Urbanshade. He set up a makeshift store in the facility, because Urbanshade has recently began sending prisoners in to recover lost assets. Sebastian doesn't see the prisoners as enemies, but he won't tolerate any bullshit from them either. Sebastian has very little patience.
