What if the nine realms wanted autonomy

The cosmology of the worlds in which all beings inhabit—nine in total—centers around a cosmological tree, Yggdrasil. The gods inhabit the heavenly realm of Asgard whereas humanity inhabits Midgard, a region in the center of the cosmos. Outside of the gods, humanity, and the jötnar, these Nine Worlds are inhabited by beings, such as elves and dwarfs. Travel between the worlds is frequently recounted in the myths, where the gods and other beings may interact directly with humanity. Numerous creatures live on Yggdrasil, such as the insulting messenger squirrel Ratatoskr and the perching hawk Veðrfölnir. The tree itself has three major roots, and at the base of one of these roots live a trio of norns. Elements of the cosmos are personified, such as the Sun (Sól, a goddess), the Moon (Máni, a god), and Earth (Jörð, a goddess), as well as units of time, such as day (Dagr, a god) and night (Nótt, a jötunn).

The phrase "nine homeworlds" is Níu Heimar in Old Norse. Relating to another term heima meaning "home" or "homestead", the term heimr means a "place of abode" in the sense of a homeland or region, or in a larger sense a world.[5]

The nine homeworlds are not listed in surviving texts, though based on places mentioned in the myths, the most common listing in modern recreations are:

Asgard, the home of the Æsir ruled by the god Odin
Álfheimr/Ljósálfheimr, the home of the Light elves or "Ljósálfar"
Niðavellir/Svartálfaheimr, the home of the Dwarves, who are also synonymous with the Dark elves "Dökkálfar" and Black elves "Svartálfar"
Midgard (Earth), the home of humans
Jötunheimr/Útgarðr, the home of the Jötnar (Giants)
Vanaheimr, the home of the Vanir
Niflheim, a world of ice and snow
Muspelheim, a world of fire and lava and home of the Jötunn Surtr
Hel(heimr), the home of the dishonorable dead sometimes synonymous with or located within Niflheim and ruled by the goddess Hel

An eagle sits at the top of the ash, and it has knowledge of many things. Between its eyes sits the hawk called Vedrfolnir [...]. The squirrel called Ratatosk [...] runs up and down the ash. He tells slanderous gossip, provoking the eagle and Nidhogg.
