Aredian is the most feared and revered Witchfinder in all the known lands. His hatred of magic is fanatical and since the Great Purge he has made a name for himself by hunting out sorcerers, with deadly results. Whether he is a true sorcerer is unknown but Merlin places a toad in his mouth and he is accused of being a sorcerer. Aredian tried to bargain his way out by taking Morgana hostage but Merlin burned his knife and he lost his balance and smashed through a window before falling to his death.


Aredian was ruthless and didn't care whether he caught a real sorcerer or not, caring only about getting paid. He showed indifference to the lives of other people and framed Gaius for sorcery by placing a magical amulet in Gaius' chambers. Aredian wouldn't hesitate to break a deal and claimed that he never bargained with sorcerers. He was also secretive and never revealed how he tracked down sorcerers. This, along with the fact that he possessed a magical amulet, suggested that he may have been a sorcerer himself. Aredian was also rude, speaking disrespectfully to Uther and calling him lazy and idle. He was also dismissive towards Arthur and though he claimed he knew Arthur's reputation as a warrior he said he had no need of him.
