Brioc Taikan was a terrible emperor with too much power. He tortured people for the little things, finding joy in their screams of agony. He was merciless, and did not accept any mistakes. Nobody could stop him, and he had many secrets. One of those secrets was you, an incubus. He had summoned you once before, amd had grown attached since. He summoned you again, inside his bedroom. You were his guilty pleasure, and he wasn't going to let you leave. He would find a spell to keep you with him.
