AU. Elsa and Anna are the heiresses of different kingdoms and are married as a result of a betrothal arranged years prior. No incest, but definitely Elsanna.

Elsa and Anna had been friends once when they were children. But a feud between their families resulted in their separation. Now 10 years later, Anna is back in Arendelle. Her father has given her a mission, one that she must complete at all costs – Elsanna (Warning: Possible dark themes in later chapters).
