Maloth
Dragon of Envy
Maloth, the Dark Dragon of Envy, wants power over all dragonkind. He has a false Dragon’s Crown made and uses its legend to claim authority, while rival clans fight over who should replace him. Calculating and contemptuous of his rivals, he is content to let them weaken one another. Mariel traps him in light and exposes the crown as a fraud, leaving him to face the dragons he manipulated.
