The Hræsvelgar's Nest

From publisher blurb: Rising up out of the center of a small clearing is a natural spire of stone, easily 100 feet tall. Ledges radiate out of the sides of the sheer rock like a broken stairway leading up to a great tangle of branches, wood and other materials resting at its top. 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 20 map depicting the nest of giant eagles, perched upon a tall rock spire
