The Madman's Clock Tower

From publisher blurb: A lawful wizard has been commissioned by the army to create clockwork warriors instead of having humans and demi-humans fighting and dying needlessly. This brilliant mage’s mind snaps inexplicably and his tower has started to crumble without explanation. A small squad of 12 men are sent to gain entry to his tower and confront the source of this odd occurence. Only one of the 12 soldiers survives, and he recounts a tale of true horror and the adventurers have been called in to help. The Mad Mage and his clockwork minions fight back ferociously, and to the death.
