Backstory: Leader of the Yellow Mask gang and spy for the nazis during World War 2. The Purple Priestess whose name was on reality Sinestra, was an opportunist who was driven to do anything regardless of the consequences so long as she could get ahead. Regardless of how many were crushed underfoot to make it happen.
Using auburn teas to render her victims unconscious and a black room which uses electrical current to paralyze those bound within it, Sinestra would have her Yellow Mask gang kidnap her victims families and beat them a bloody red until she could get the top secret information to sell to her superiors.
After World War 2 ended, the Purple Priestess would create a religion heavily inspired by the Crimson Cult, convincing people to grant her their fortunes for the promise of miracles.
Fleeing to the windmill laden country of Zarikan when the consequences of her own actions begun to catch up to her, the Purple Priestess would discover the local religion to Vultura, goddess of underground waterways which were the key to the nations existence. Subtly getting rid of the leaders of the cleregy through means most nefarious, Vultura would claim herself to be the voice of Vultura and use that religious authority to kidnap princess Alura, daughter of the nations king Yuka and proclaimed her to now be in service to the goddess.
The Purple Priestess would then demand regular tribute of gold and wealth, threatening the wrath of the goddess Vultura, bringing about an end to the nations water supply should they fail, dooming the people of the nation.
