Right now, the problem is that there are too much magic in the ecosystem but no depredator to consume it.
The Elder Dragons have played a vital role in this system for centuries, consuming the magic and making the cycles works.
The addition of Aurene and her power to consume all kinds of magic have give us hope, but using her as a toilet for magic would be, in my opinion, a poor writing solution.
So how can we stop this cycles?
Taking enough magic outside the system.
Do not call me crazy yet, because it is have been done before. The Seers crated the Bloodstones, solid red cristaks of magic out of the reach of the Elder Dragons.
Should we find out how the Seers created them, and cmake new ones?
Could this be a solution for the ED cycle problem?
