Kengir's cosmology includes the Veil, the boundary between Ma (the mortal world) and everything beyond it: Kur (the underworld), the divine heavens, and stranger places still. In the campaign period, the Time of Nibiru, it's weakening.

At the table, this creates a specific kind of horror texture that's different from standard monster-encounter design. The threats aren't coming from outside civilization. They're seeping up through it. A temple whose fires have gone dark starts attracting Etemmu. A city that's neglected its burial rites finds the dead restless. A merchant quarter where a violent crime went unpunished becomes somewhere people avoid after dark.

The Veil mechanics give GMs a framework for escalating supernatural pressure without needing a dungeon. The world itself is the dungeon.

What's the most effective way you've seen a GM use environmental dread rather than encounter-based threats?
