Remember the good old days, when adventures were underground, NPCs were there to be killed, and the finale of every dungeon was the dragon on the 20th level? Those days are back. Dungeon Crawl Classics adventures dont waste your time with long-winded speeches, weird campaign settings, or NPCs who arent meant to be killed. Each adventure is 100% good, solid dungeon crawl, with the monsters you know, the traps you remember, and the secret doors you know are there somewhere. Chaos reigns in the kingdom as the king and queen have died, leaving no heirs. The heroes are commissioned to go into the kings vault to retrieve the scepter of succession, a magical relic that legends claim to be able to determine who should be the rightful ruler of the kingdom. The king kept his treasures in no ordinary vault, however. The so-called Vault of Rings was designed to not only keep out thieves but to train his heir, who would be unable to access the kingdoms wealth until he or she could overcome the trials and obstacles found within the vault... This special module marks the fiftieth adventure in the Dungeon Crawl Classics series. The adventure features a unique map composed of concentric rings that rotate as the characters explore the dungeon. The module is printed to include a map on the inside cover that physically rotates, so the DM can follow the dungeon rotation as the players explore. If you enjoy this adventure, look for the rest of the Dungeon Crawl Classics series!
