After novices graduate from school, they receive a promise mark as a sign that they've finished their training. When Rose dropped out of school to hunt Dimitri and met Viktoria, Viktoria mentioned that those without a mark were the "unpromised." It was so unheard of that there was no term for it. Rose describes it looking like a "twisting line, sort of like a snake." In Spirit Bound, Rose describes her promise mark as a stretched out S in the middle of the back of her neck with curling ends that wrap around her molnija marks "like an embrace".
