 The conflict is only ended when Tassadar demonstrates the effectiveness of the dark templar against the Zerg.With Raynor, Zeratul and Fenix, Tassadar breaks through the Zerg defences on Aiur to the Zerg Overmind; Tassadar channels both his own psionic energies and those of the dark templar through the hull of his flagship and crashes it into the Overmind.The resulting discharge of energy destroys the Overmind and transcends Tassadar to a new level of spiritual existence; Metzen refers to this transformation as becoming a "twilight messiah".
