A dwarf (pl. dwarfs or dwarves) is a type of supernatural short human-shaped being in Germanic folklore. Accounts of dwarfs vary significantly throughout history. They are commonly, but not exclusively, presented as living in mountains or stones and being skilled craftsmen. In early literary sources, only males are explicitly referred to as dwarfs. However, they are described as having sisters and daughters, while male and female dwarfs feature in later saga literature and folklore. Dwarfs are sometimes described as short; however, scholars have noted that this is neither explicit nor relevant to their roles in the earliest sources.

Dwarfs continue to feature in modern popular culture, such as in the works of J. R. R. Tolkien and Terry Pratchett, where they are often, but not exclusively, presented as distinct from elves.

Týr (/tɪər/; Old Norse: Týr, pronounced [tyːr]) is a god in Germanic mythology and member of the Æsir. In Norse mythology, which provides most of the surviving narratives about gods among the Germanic peoples, Týr sacrifices his right hand to the monstrous wolf Fenrir, who bites it off when he realizes the gods have bound him. Týr is foretold of being consumed by the similarly monstrous dog Garmr during the events of Ragnarök.

The interpretatio romana generally renders the god as Mars, the ancient Roman war god, and it is through that lens that most Latin references to the god occur. For example, the god may be referenced as Mars Thingsus (Latin 'Mars of the Assembly [Thing]') on 3rd century Latin inscription, reflecting a strong association with the Germanic thing, a legislative body among the ancient Germanic peoples. By way of the opposite process of interpretatio germanica, Tuesday is named after Týr ('Týr's day'), rather than Mars, in English and other Germanic languages.

Norse cosmology is the account of the universe and its laws by the ancient North Germanic peoples. The topic encompasses concepts from Norse mythology and Old Norse religion such as notations of time and space, cosmogony, personifications, anthropogeny, and eschatology. Like other aspects of Norse mythology, these concepts are primarily recorded from earlier oral sources in the Poetic Edda, a collection of poems compiled in the 13th century, and the Prose Edda, attributed to the Icelander Snorri Sturluson in the 13th century. Together these sources depict an image of Nine Worlds around a cosmic tree, Yggdrasil.

In Norse mythology, Ask and Embla (Old Norse: Askr ok Embla)—man and woman respectively—were the first two humans, created by the gods. The pair are attested in both the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, composed in the 13th century. In both sources, three gods, one of whom is Odin, find Ask and Embla and bestow upon them various corporeal and spiritual gifts. A number of theories have been proposed to explain the two figures, and there are occasional references to them in popular culture.

In Norse mythology, Líf (identical with the Old Norse noun meaning "life, the life of the body") and Lífþrasir (Old Norse masculine name from líf and þrasir and defined by Lexicon Poëticum as "Livæ amator, vitæ amans, vitæ cupidus" "Líf's lover, lover of life, zest for life"), sometimes anglicized as Lif and Lifthrasir, female and male respectively, are two humans who are foretold to survive the events of Ragnarök by hiding in a wood called Hoddmímis holt and, after the flames have abated, to repopulate the newly risen and fertile world. Líf and Lífþrasir are mentioned in the Poetic Edda, which was compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. Many scholars have speculated as to the underlying meaning and origins of both names.

In Norse mythology, the Æsir–Vanir War was a conflict between two groups of deities that ultimately resulted in the unification of the Æsir and the Vanir into a single pantheon. The war is an important event in Norse mythology, and the implications for the potential historicity surrounding accounts of the war are a matter of scholarly debate and discourse.
