The Great Disc world and mirror of worlds
9th of Pellar, 835 AC
On the outskirts of the Prime Material, there is a realm unlike any other - world and mirror of worlds. Held aloft by the branches of Yggdrasil, the World Ash, the Great Disc is just that - a flat, circular world, ten thousand miles in diameter, garlanded by an endless waterfall at its vast circumference and domed by the starry vault of its own firmament, itself a reflection of the endless Astral Plane beyond.
