A loose adaptation of the classic "Expedition to the Barrier Peaks" D&D module, this dungeon starter gives you everything you need to start an adventure that introduces sci-fi elements like spaceships, little green men, and laser guns into a classic dungeon delve.

This campaign front helps you expand 'The Pierced Firmament' into a complete campaign by outlining the ambitions of two casts of villains - the invading aliens from outer space and the vain king leading the efforts to fend them off.
