The powerful Kingdom of Prythia's heir, Theya Ashborn, pronounced dead after fleeing from her kingdom and her black magic, is attempting to find a healer to fix her, to cure her. Upon arriving at the Kingdom of Igocia, she is vowed by the monarch himself, Silas--never to be called Riki--that he would assist her in finding control over her power. In contrast, there is one condition: while he provides help, she must act as his trusted confidante and his stealthy thief--both in secrecy.
