The Ur-Flame

Created by beasts called The Ur when seeking to be more like birds. They attempted to kindle the Divine Flame generations before Sibecc and failed drastically in a way that wiped them out in the resulting magical surge. They did manage to make a Flame of sorts though, The Ur-Flame. It is basically a warped opposite of the original Flame. It seems to be able to undo that specific magic rending apart the essences of a Flame-Touched or similar being, potentially even removing sentience granted by the Flame. When Nippur was near it he could feel his cat and human sides warring within him. When Matthias had "Scarlet" bring him the Ur-Flame the contact with it caused his nature as a Mojh to fracture and he became a disjointed mix of man and dragon, though Tokka was able to undo the physical changes. It seems there might be more to the magic of the Ur-Flame as when Nippur though it back in the pit with the desiccated Ur, the dead creature appeared to reach forward and grasp the flame back to itself. The group then sealed the pit with a boulder.
