The Ashen Kingdom
A ring to force one's will at the expense of another
Hegemony is a cruel ring. When worn, it can drain magic from other mages, lifeforce from almost anything, or just energy from the environment. This process can be dangerous, but the payoff is great. The ring, when charged, boosts magic in unexpected but always helpful ways.
The ring has a tendency to whisper ideas, none of them good.
This ring was an early work of Archmage Welk, who was later disgraced for dabbling in water magic. It was given to one of his favorite students.
