Kolr
Former Champion of Fire
Kolr is a former Champion of Fire whose demand for recognition becomes a desire for Fiamme’s death. He fled Aleister’s flames and died calling for her help. Fiamme dismissed him, erased his name and recast his story to glorify herself while his soul remained ignored in the Plane of Fire. According to Fiamme, his theft of the Magnum Opus flames was an attempt to force her to acknowledge him and his ordeal.
Her eventual embrace and apology cannot satisfy that demand. Kolr continues to call for her death. Aleister later says the stolen flames incinerated his soul, leaving only will and hatred to form a mindless remnant.
