When two stags have a fight, they clash antlers, inflicting grievous wounds on the body, occasionally fatal ones.
When two Changelings fight, it can be similar. It is more often a clash of words and blades than antlers but it is not unknown for antlers to lock, and however they fight, the wounds are no less severe.
When rage takes them, it can be all the worse. And when they are family, the wounds cut all the deeper.
When a Changeling turns her wrath on her fatally-wounded brother, both beset by madness, it can be disastrous. The prongs of the antlers go deep and cause even worse damage, hastening the end.
