Stone and Rock

Concept: “Searching for a lost treasure in a cave at the base of a mountain, wrong turns in a maze of tunnels only took you fumbling deeper into the earth.”
Content: An abstract dungeon bursting with content
Writing: Copious instructions for travel, tables for encounters, stat blocks for denizens, and some unique loot
Art/design: Background adds color and character, but mostly devoted to text
Usability: Much enhanced by arrows connecting relevant sections of text
