Origin
Going by the name of Freidrich Mathers, the Trueblood Drago had two children: Thomas and Sela. After he refused to return to the Dark One‘s forces, his carriage, with Thomas and Sela in the back, was sabotaged. Thomas fell out immediately and Drago and Sela went over the edge. Hanging on by a rope, Drago sacrificed himself to safe Sela. He let go off the rope, so Sela could climb up safely.
