The Oathbreaker ritual began as a spell, allowing the broken oaths to "come home to roost." As knowledge was lost, it evolved into a ritual for having someone legally proclaimed outside the protections of various laws and Mercenary Guild codes. After Kethry speculated that it must have been a spell at one time, Jadrek found the original version for her in early histories. They used it on the usurper King Raschar, opening the way to the land of the dead, and allowing Idra to take her revenge on the brother who tortured and killed her. (Oathbreakers)
