Publisher's blurb: Wooden walkways and lookouts span the darkness of this underdark gorge, clinging to stone pillars or the hollowed-out cliffs in which living quarters have been built. Twisting stone tunnels lead to rooms filled with strange alchemical equipment, seer’s orbs and bookshelves full of esoteric secrets. Other tunnels lead to a tavern full of tables, food and good ale as well as storage areas.
