Narses's servant - Ifrit

Inspiration from "The Inquisitorial Cycle" - a series of stories and novels by Jacek Piekara about the adventures of the inquisitor Mordimer Madderdin, published by Fabryka Słów. It's set in an alternative version of our world where Jesus Christ descended from the cross, punished his persecutors, and those who did not believe in him.

The character is one of the servant of powerful Persian sorcerer Narses, renowned for his vast knowledge and cruelty; however, he was later captured by the Inquisition and, due to memory erasure and mind reconstruction, became a faithful servant of Christianity.
