Eikhallr - The Hall of the Oak

From publisher blurb: Massive stone pillars flow upward into oak and yew trunks, which spread into a gently swaying canopy overhead. Stars glitter through the branches and leaves, and the sky beyond is an unending void. A printable battlemap compatible with any RPG/Dungeon-Crawl game. Use as a standalone gameboard, or combine with any same-scale tileset. Contents: A 20 x 30 map depicting a hall, existing in the dream real of Draumheim
