The Double Skulls: Tavern Tales – Book OneExpansion

From BoardGameGeek:

The Double Skulls Tavern Tales unofficial expansion for Heroquest is a deck of 16 large 8x10" cards 9 Double sided dungeon cards 6 Quests - also printed on the cards to look like an old book. Each quest details the card placements to make up the quest board and details enemy placement along with any other scenario based elements or enemy upgrades that may be in that quest. These dungeon cards can be used to make up your own adventures and the lack of the one width corridors really opens up exploration and team placement when heading into unexplored areas. -description from the designer
