In a universe where Demons rule the earth and humans are their slaves, a small village girl somehow gets the attention of the king of the world....

She's always seen him. She's seen him strong, and she's seen him broken. And now he's seen her too. It is an odd romance, one between a servant and a prince, but one that survives until the end of time. This is their journey together, the journey of Sigyn and Loki.
