Tsagaz
A pre-cataclysm dwarven ruin, located on what is now an island in the Sea of Dreams. Once owned by the Bargachin clan (a thoroughly heterodox clan). Not a clan hold, but a research facility into construct-based immortality. They built humanoid-ish constructs (like the soul-forged bodies, except more mechanistic). Tried to bring them to life by transferring minds into them, mostly failed (transferred memories and fragmentary personalities, but not the soul or the will). Some have now, post Fourth Wish, come to life of their own.
Previously populated by three factions of constructs--the Yavakh, the Uldekh, and the Unawoken. The Unawoken were unthinking constructs that cannibalized the awoken ones, controlled by Morlan Metalbender. With his destruction, their threat is ended.
Explored by the Vault Seekers in summer 250 AC, after which only a few of the Uldekh remain. The majority were slain in combat with the Unawoken and the Vault Seekers. The Yavakh have decamped to Honedaxe.
