He is quite a weird, creative and quirky guy. He is a survivor treated as a quasi-entity. Maybe he is a real entity. He imparts various knowledge to explorers. He is famous for his avatar of a sheep with a machine gun. He doesn't tell you what he doesn't tell you firmly. All the backroom documents with no exit were contributed by him. His nickname is 'Alucard81'. He claims to be a normal human being too, and is somewhat reluctant to idolize himself.
