Norse Gods

The Norse Gods are a pantheon of deities central to all accounts of Norse mythology. The principal pantheon of the Norse gods is the Aesir (pronounced 'ICE-ear', traditionally spelled Æsir), whom are connected to power and conflict, while a second pantheon comprises the Vanir (pronounced 'VAN-ear'), whom are associated with cultivation and fertility. In Norse mythology, the two clans waged war against each other, ultimately resulting in the eventual unification of the two pantheons.

 * Mímir - Guardian of the Well of Knowledge (similar to Loki, not always counted as an Aesir).

Abilities, limitations, and weaknesses
The Norse gods have extreme longevity, with superhuman physical abilities and a variety of magical powers. Because the Norse gods are physical beings (like the Greco-Roman gods and unlike the Egyptian gods), they are able to sire demigod children with mortals.


 * Apple-Induced Youth: The Norse gods will rapidly grow old and weaken when they're unable to eat Idunn's apples of youth on a regular basis, shown when she was kidnapped by Utgard-Loki on one occasion.
 * Mortality: The Norse gods are extremely difficult to kill (Mimir survived being decapitated, for instance) but they, unlike the Greco-Roman gods, are not completely immortal, as most of them are destined to die during Ragnarok, the Twilight of the Norse gods. Beings or weapons with the power to kill Norse gods include the following:
 * Other gods, since Loki and Heimdall are destined to kill each other.
 * Surt, the Lord of Muspellheim, who is destined to use Sumarbrander to kill Frey.
 * Fenris, the ferocious wolf, who is destined to kill Odin; his two sons, Sköll and Hati, are also about to kill Sól the Sun and Máni the Moon after which Ragnarök would come.
 * Garm, the blood-stained guard dog of Hel, who is destined to kill Tyr.
 * Jormungand, the World Serpent, who is destined to kill Thor (though he will also be slain in the process).
 * Mistletoe that killed the otherwise invulnerable Baldur.
 * Thor's hammer Mjølnir, as he had threatened to kill Loki with it several times.

Trivia

 * The only Norse deities who can shape-shift appear to be Odin and Loki, though Frigg is able to also do so in the myths via her falcon cloak.
 * It's unclear if Surt is capable of killing Frey without the Sword of Summer.
 * The Norse gods are the first pantheon introduced in Riordan's books whose existence is not tied to western civilization.
