The Tangad-Sin were Tragarans that left Lanirûk in the Horgon Era. They were against the city-state's policies in relations to other peoples. They were known to join with the minotaurs in their often mutual conflicts with Lanirûk; battling the advance of the civilization northward up the Imrabêl valley.
The Tangad-Sin turned to more civilized ways in the First Epoch. There first permanent settlement was Tani-Tur.
