Ah, don't worry, it's backed up by her her back story. Mixing dark magic, nasty potions and the nutso-religious, semi-primeval village she was born in tends to do funny things to people..
They were all a more-or-less crazy there, sort of like a cult, if you will, they came together after the Exodus. The group was small, four children, twelve adults. When some investigating by the Inquisition as to their religion and values was made they scattered and ran and the village was broken and was mostly written off as unimportant. At this time, my char was about twelve. She got her head knocked in the scuffle and was left behind by her (coo-coo) parents, instead being picked up by a writer who was visiting the village for research at the time. He dropped her in the nearest town with some nuns and bada-bing-bada-boom, sadistic, purple-eyed, heretic emerges.
Sorry for the wall of text.. I like writing little stories like that :3 Please advise if this breaks any of the Lore and I shall immediately remedy it.
