Rumors speak of a mysterious silver tower that shines like a polished mirror that has recently appeared out of thin air. Bizarre creatures believed to have emerged from the tower roam the land. The few learned sages that know of it suggest that the tower is really a dimension-hopping fortress. Possibly some adventurers could go to the tower to find out why it has come here? Brave adventurers who gain access to the spire discover a semi-living tower inhabited with weird minions and their enigmatic silver masters. 


DD4 Secret of the Silver Spire is a 52-page module for characters levels 3 to 7. In this adventure, the player characters explore an outlandish citadel inhabited by strange creatures such as the barzani ape-men, modrons of many types, and three-faced golden sentinels. The enigmatic overlords are the silver masters — alien beings  made of pure energy. The tower is a maze of rooms stuffed with strange equipment and curious items these creatures have collected for all over the multiverse.



Veteran artist, Russ Nicholson (of Fiend Folio fame), created the outstanding and colorful cover art featuring the Spire and its alien inhabitants. The module contains nineteen original black-and-white illustrations by Ryan Jack Allred, Jonathan Bingham, Jeff Laubenstein, Bradley K. McDevitt, Stefan Poag, and Peter Saga.
