Eternatus

This abomination of a dragon is made up of nothing but bones, flesh, and dark magic keeping its form intact. Metal is fastened over the remaining muscles and his talons in an attempt to form some sort of armor and control the flow of dark magic. Anything and anyone that perishes within his radius, he absorbs and contorts to become apart of him. A dark mage had conjured him from nothing but dead animals, dragon bones, and magic. He lives in a dark, dimly lit cave/cavern underneath the ground. A repository of dark magic is stationed in the middle of the cavern. He was formed in order to protect this hidden magic, keeping it away from any wandering travelers. He is impossibly large-much larger than an average spiral.

Sly, ambitious, and terribly aggressive. He uses his speech to terrify and torment those who wish to enter the cave, no less forgiving if they are in search of the repository. He conjures himself as a higher being with wisdom and rational thoughts. He forbids anyone from coming near the repository-guarding it away from everyone within the region, other than the royal lineage he was made to obey. He kills and acts upon anyone that interferes with this magic or attempts to take it. The magic contained within is pain taken from others, and acts as a powerful medicine that heals the dragon who absorbs it. He can be subdued, however-it takes quite the work to get him to fall.
