The Stormglass Theft

During last night's storm, someone broke into Professor Quill's laboratory and stole the Stormglass Heart, a crystal that holds the fury of a lightning strike. The thieves left soot, footprints and a scrap of white fur. Follow the trail from a smoking lab to a moonlit clearing where hired blades wait for a teleport circle to wake, then on to a hall on the frozen river where a cult of the Pale Moon is packing its sledges. They don't want the Heart for its value. They want it for what it can break open.

GM Summary: A one-shot for four level-3 characters, around 3 to 4 hours. A pale cult leader hires a bugbear's crew to steal the Stormglass Heart, a crystal that stores lightning, because only lightning can break the seal on an ancient jungle tomb. The party tracks the theft from Quill's lab through a teleport circle to the cult's frozen hall, then races through the circle again to stop the Ash Prior before the seal breaks and the storm inside wakes. Four scenes: investigation, an ambush, an infiltration and a timed.
