The Byeshk Mountains have long been controlled by extended harpy clans. Though the Rotwing, Last Dirge, Carrion Caller, and Stormsinger flights have all migrated to the interior to serve the Daughters of Sora Kell, others remain in the mountains, including the Brass Talons, the Forgotten Choir, and the Crimson Wind. The largest and most dangerous of the mountain flights is the Wind Howlers. The Howlers’ leader, Callain of the Bloody Word, despises the hags and interferes with their plans at any opportunity. All the mountain clans prey on unwary explorers and travelers.
