Agents for the Mayor of Kleine have discovered the stronghold of the Red Hand goblins deep within the Burning Hills. They have also discovered that the goblins are forming an alliance with local hobgoblin and bugbear tribes to sweep the humans out of Thunder Rift forever. The PCs must reach the lair before the hobgoblin and bugbear agents return to their own tribes. if the envoys do not return, the tribes will assume that the goblins murdered them and attack the goblins instead of the human settlements. In this way, the humans of Thunder Rift gain some unexpected allies against the Red Hand goblins. This is the most dangerous and demanding of the three adventures in this set. It is recommended that you play it after Red Hand Trail and Trouble Below. However, it can stand alone as an adventure in its own right if you wish. Part of TSR 1076 The Goblin's Lair
