Tacig in the Tarn language translates to Chosen ones of Glory. The Tacig are basically warriors who know they are going to die for the honor of the Tarn. Tacig can only be named by an unbroken circle. The Gadin wanted to declare the warriors who detonated the atomic weapon at the Human city called Federation Battle Station Torgu-Va as Tacig despite their circle being broken.
