This download includes both the hi-res DM's and Player's versions of Map 2 from the entry level D&D scenario Danger at Darkshelf Quarry by Skip Williams; included in the classic RPG adventure compilation Against the Slave Lords.
In addition to the full-page DM's version, you also get the huge 3600x4500 pixel untagged player's version that's optimal for large format home printing or screen display. Purchase it now to help run the adventure or use it on its own and spice up your home brew game night.
