He is… well was… one of the finest historians in all of Terrania, but was charmed and swindled by Anja; who trapped him inside this pocket domain, which the mirror acts a conduit to. Inside is stacks and stacks of books. He said Anja would dump books into his realm and “persuade” him to pour through them to compile knowledge; and act as a resource when ever she needed it. He asks the party to take the mirror, and offers to help them as much as he can if they agree to try and find a way to release him.
