List of Norse Mythology References in Halo

In the Halo Universe there are several references to Norse Mythology or simply the Norse people. Below are a few of them.

Norse Characters
Loki; Loki (Also known as Mack) was an A.I. on Harvest who could shift shape. Loki in Norse Mythology was the god of chaos and treachery and could shift shape like Mack. Additionally, he was also infamously known to be a trickster much like Mack.

Sif: Sif was another A.I. on Harvest and was often annoyed by Loki. In Norse Mythology, Sif was the wife of Thor and was the goddess of wheat and fertility. Ironically Loki stole her hair in a Myth.

Jotun: Jotuns were machines used on Harvest. Mythologically, they were giants.

Munin and Hungin: Two seas on Harvest, they are named after Odin's two pet ravens.

Norse Locations
Utgard: Utgard was the capital of Harvest. In Norse mythology, Utgard was the stronghold of the giants.

Bifrost: Bifrost was a bridge that connected Midgard and Asgard.

Valhalla: Vahalla is a map on Halo 3. In Norse mythology, Valhalla was a place where fallen warriors went to battle all day and feast all night, forever, fitting for the game.

Vigrond: Vigrond Highlands was a place near Utgard on Harvest. In Norse mythology it's the plains where Ragnarok is said to take place.

Gladsheim: Gladsheim Highway is named after Gladsheim in Norse mythology where Odin's hall is.

Ida- Ida is named after the plains in Asgard.

Norse Objects
The Index: The Index is supposedly similar looking to Thor's Hammer.

Spartan Laser: On the Spartan Laser there is the symbol for Gungnir, the spear used by Odin, the Norse god of war.

Skidbladnir: The UNSC Skidbladnir is named after the ship made by Loki to fit all the Gods. It was also small enough to fit into a pocket.

MJOLNIR: The MJOLNIR armor, that is designed specifically for the Spartan-II's, is also the hammer of Thor. Mjolnir translates simply to "crusher", referring to the hammers pulverizing effect. The hammer also shot bolts of lightning, since Thor was the Norse god of lightning, as well as the son of Odin, the god of war.

Other
Berserk: Sometimes a Brute goes on a rampage nicknamed "berserking". The Norse had warriors, called Berserkers who were followers of the cult of Odin (the one-eyed Norse god of war) and believed in the importance of a warrior dying heroically in battle rather than shamefully in his bed. They were said to have been immune to pain and possess uncontrollable aggression, and fought wearing only bear or wolf skins, entering a trance-like state before battle. The berserker's behavior seems to come from ingestion of drugs such as alcohol before combat, although that would make them difficult to use on the battlefield, similar to the Brutes from Halo 2 as well as Halo 3.
