From publisher blurb:
An expansive dungeon built under the ruins of Greystone Castle - it's easy to get lost!
Seven years ago we listed our first map on DrivethruRPG; Greystone Dungeon. To celebrate our 7th Birthday, we've returned!
A printable rpg battlemap compatible with any RPG/Dungeon-Crawl or skirmish game. Use as a standalone gameboard, or combine with any same-scale tileset. The map is 50x50, equivalent to 25 of our standard 10x10 tiles.
Contents: A huge, expansive abandoned dungeon. Parts of the dungeon were built under Greystone Castle, including a prison, cellars, an undercroft and crypt. However, later users of the dungeon have expanded it to include catacombs and an arcane laboratory/temple.
