Nine Realms

The Nine Realms are a group of nine celestial entities. Interconnected by the branches of Yggdrasil, the realms orbit Midgard.

Prior to its destruction, Asgard was considered the head of the Nine Realms.

The Convergence

The Convergence is an event that occurs every five thousand years, where the physical boundaries between each realm in the Nine Realms ceases to exist.
