The Forbidden Caverns of Archaia will keep your players on their toes and your campaign going strong for years. FCoA is brought to you by the Old School Renaissance (so don’t forget your 10’ pole).

The country of Rhyl has been beset nearly every night for many years by a large, terrible creature that flies out from the mountains near the city of Asereht. Nearly a year ago the creature broke through the wall of King Namreh’s castle and carried off the king’s son, Prince Laechim, along with a large amount of the royal treasure. After the creature’s raid on the castle, King Namreh ordered his army to search the mountains and discover Astylis’ complex. The soldiers made two forays into the mountain wilderness, but each time were harassed and eventually driven back by goblin raiders. Since the failure of the second assault, the king has taken to commissioning small parties of mercenaries and adventurers, sending them into the mountains with promises of great reward upon the completion of the rescue mission. For reasons which the king has never found out, none of these rescue parties has ever returned to Asereht. Your party is now attempting to be the first. Pgs. 37-44
