DragonLance: A Jumpchain Sourcebook

From the introduction: Another world, another adventure. Another reality to explore, a thrilling new … library? A library, complete with the faintly musty smell of old tomes. Long tall stacks of books, scrolls, and tablets run the length of the chamber you find yourself in. Seated at a desk near the back of the chamber is a lone figure. He scratches away with quill and ink on a scroll, pausing only to wet his quill in a small inkpot and look into a crystal globe located to his left.
