The Norn are... a group of immortal female Jotunn — Frost Giants, for the most part. When every creature is born, they fix a chain around them that only Norn and certain other immortal creatures can see. This chain tells what that being will do, in their lives, and how long they'll live.

[Diplomatic or not, her expression says that this doesn't agree with her.]

They enforce Fate, and prophecies.
