Linn Regiostar founded the Church of Alexander Mark, though he's probably better known these days for dying in one of his own dungeon traps and becoming a ghost. The guy was obsessed with RPGs and dungeon crawlers—so obsessed that he actually built a massive dungeon beneath his church, funded entirely by the church's donations. He eventually fell victim to a poison arrow trap while exploring it, which is pretty much the most on-brand death possible for someone like him.
Before all that, he was a huge fan of classics like Ultima and Dragon Quest. He apparently had such reverence for the Ultima series that he styled himself as Akiba's answer to Lord British. (Fair warning: some translations of his name render it as "Rean Radiostar" instead of Linn Regiostar, depending on the source.)
