When Shadrak the Unseen steals a magical ring from one wizard on behalf of another, his life quickly goes from bad to worse.

Before he can deliver the ring, an invisible thief snatches it from him, and flees to the city of Jeridium.

Soon, everyone and his dog has designs on the ring, but its promise of power leads only to disillusionment and death, and the ring is revealed for what it really is:

A snare for the unsuspecting.

A lure that leads to the undead clutches of the Witch Queen of Tho-Agoth.
