Lith's touch remained gentle but he clenched his teeth as he pulled the Void and the Dragon apart by sheer force of will. Lith assumed his Tiamat form, roaring at the top of his lungs while also conjuring a Hush zone to protect everyone present.
He had done this plenty of times before but now it was different. His voice was still filled with rage, pain, and hatred like in the past, yet he wasn't screaming to fan their flames.
He wasn't igniting his past traumas to open his old wounds and draw strength from them. Lith's roar was meant to express those feelings and let them go. He was letting them burn away, because, in the end, everything burns, even hatred.
Lith yelled for all of the people he had lost, the pain he had endured, and the betrayals he had suffered. In his long, primordial roar he let them go, refusing to carry their burden anymore.
