Sandra was born in the city of Martholin as a warrior monk. She grew up studying the Gaddocks teachings developing an aggressive disdain for jehts and their apparent demonic history. Sandra would train to become a Ridder and rose through the ranks to eventually become a captain. She would befriend another captain named Emil and the two would bond over their hatred for jehts and love for Gaddocks teachings. Emil would eventually share her story about the young “demon” who grew up in her hometown of Nionlah and killed her friend Niraku. This would fuel Sandra’s abhorrence towards jehts.
