the cosmos. The tree's branches extend into various realms, and various creatures dwell on and around it. The gods go to Yggdrasil daily to assemble at their things, traditional governing assemblies. The branches of Yggdrasil extend far into the heavens, and the tree is supported by three roots that extend far away into other locations; one to the well Urðarbrunnr in the heavens, one to the spring Hvergelmir, and another to the well Mímisbrunnr. Creatures live within Yggdrasil, including the dragon Níðhöggr, an unnamed eagle, and the stags Dáinn, Dvalinn, Duneyrr and Duraþrór. Nine Worlds Old Norse texts mention the existence of Níu Heimar, translated by scholars as "Nine Worlds". According to the second stanza of the Poetic Edda poem Völuspá, the Nine Worlds surround the tree Yggdrasil. As recalled by a dead völva in the poem: The Nine Worlds receive a second and final mention in the Poetic Edda in stanza 43 of the Prose Edda poem Vafþrúðnismál, where the wise jötunn Vafþrúðnir engages in a deadly battle of wits with the disguised god Odin: The Nine Worlds receive a single mention in the Prose Edda, occurring section 34 of the Gylfaginning portion of the book. The section describes how Odin threw Loki's daughter Hel into the underworld, and granted her power over all Nine Worlds: The Old Norse corpus does not clearly list the Nine Worlds, if it provides them at all. However, some scholars have proposed identifications for the nine. For example, Henry Adams Bellows (1923) says that the Nine Worlds consist of Ásgarðr, Vanaheimr, Álfheimr, Miðgarðr, Jötunheimr, Múspellsheimr, Svartálfaheimr, Niflheimr (sometimes Hel), and perhaps Niðavellir. Some editions of translations of the Poetic Edda and the Prose Edda feature illustrations of what the author or artist suspects the Nine Worlds to be in part based on the Völuspá stanza above. Anthropogeny Ask and Embla—male and female respectively—were the first two humans, created by the gods from driftwood they encounter on a shore. The gods who form these first humans vary by source: According to the Poetic Edda poem Völuspá, they are Hœnir, Lóðurr and Odin, whereas in the Prose Edda they are Odin, Vili, and Vé. Eschatology Ragnarök is a series of future events, including a great battle, foretold to ultimately result in the death of a number of major figures (including various deities), the occurrence of various natural disasters, and the subsequent submersion of the world
