After the sealing of Archfey Aavalus shortly before the fall of the ken Dynasty of Avia, many Aarakocra and Uglek left their homeland in droves. While the Aarakocra splintered and fractured into many clans that spread far and wide across Tor, the Uglek refugees stayed mostly as one unified group. These Uglek called themselves the Troupeau de Minuit (or midnight Flock in common) and headed south into the figid cold of Terondar to settle its unclaimed lands.
Hundreds of years later, they now offer small beacons of warmth along the Jagged coast, worshiping Lun, Deity of Mystery and night, as well as Ugail, the Archfey Sister of Aavalus. The Uglek hospitality is unlike any other on the coast, earning them a reputation as friendly yet recluse protectors. Don't cross any of them however, as their ire can be just as potent.
