The Lantern Below Brasshall

Description

Adventure Summary

For characters of levels 3–5. Strange green lights pulse through the cracked windows of an abandoned clockwork tower, and a young noble named Serovian Vale vanished while tracing their source through the ruins below the city streets. Rumor blames a murderous inventor’s ghost or the skittering gremlins seen near the old gearworks. In truth, the tower’s apparent master is desperately containing a far worse threat sealed beneath the district, and the missing noble may be the key to either stopping it—or setting it loose.

Background

Decades ago, the eccentric inventor Ilyra Voss built a tower atop older municipal gear-chambers, filling both with experimental engines, signal lanterns, and autonomous security robots. Her final project was a void-reactive drive core that attracted and mutated the oozes lurking in the forgotten drains below. When containment began to fail, Voss locked the lower vaults and left her surviving robots with one directive: keep the seals intact at any cost. Over time, a tribe of gremlins moved in and learned that breaking the seals would doom them all, so they now sabotage intruders rather than flee them.
