From publisher blurb: Reached via The Wheel Gate on the material plane, an ancient portal, the two transitive planes are strange indeed! A printable battlemap compatible with any RPG/Dungeon-Crawl game. Use as a standalone gameboard, or combine with any same-scale tileset. Contents: A pair of 30 x 30 map depicting locations from the transitive planes. The Ethereal Plane is a foggy, blurred world, mirroring the material plane but shifted. The Astral Plane, with huge rocks churned in the Astral Sea, is truly alien.
