Catherine the Eternal

A Sorceress Queen whose magical power grows stronger by the hour rules her kingdom with an iron fist. She alone can absorb existing magic directly from the universal source known as the Mystic Cauldron, making her virtually invincible while permanently enlarging her body and soul. She can reduce her size, but only to a fixed limit, because her power keeps growing. Distance from the Cauldron does not weaken her, and she has no vulnerability. She also absorbs small amounts of life energy from her subjects, enough to strengthen herself without killing them all. Worshipped by loyal followers yet envied by others, she employs an adventurers guild to defeat enemies and detractors. When the guild investigates why magic across the kingdom is weakening, she claims others are handling it. She is lying. She is absorbing it all for herself.
