The known history of the ancient Shaftbuilder civilization, from the estimated founding of their first shafts to their abrupt fall, and the later finding of their lost sites.
Shafts are lost to history, and Shaftbuilder civilization remains hidden for millennia.
All active shafts are abandoned.
Though not the largest or oldest shaft, Kara Heraz was the first shaft found since the fall of Shaftbuilder civilization. Discovered by the ancestors of the Thaner in the Children of Aktar, the discovery of this and other Shaftbuilder dwarf ruins would come to define the Thaner for centuries.
