Starfall Chantry (OSR)

From publisher blurb:

Lurking twixt the crag-jagged hills south of Dunstone sit the ruined remains of an old dwarven fortress-temple. Rusted helms and broken blades jut from the surrounding soil like cast-off husks of iron grain, betraying the area’s violent history. Over the centuries, thousands have fought and died to possess this land, staining the earth with the blood of the slain. Three centuries ago, it took the very sky to fall to put an end to this ceaseless bloodshed. Today, however, the scars left by that same cataclysm may be enough to rekindle the old flames of war.
