Freyr

Freyr was a Vanir Chieftain, the brother of Freya, and one of the most renowned warriors to have ever lived. He was elected as High Chieftain during the Aesir-Vanir War, and was on the war council of the Alliance of the Hawk during the War of Alignment, and killed the fire giant Surtr after shattering his sword during the Battle of Vigrid.

Freyr was known for his fighting ability, his sword having a legendary reputation, as well as Gullinbursti, a boar that he rode into battle clad in gilded armor, and his magical ship Skíðblaðnir. Aside from these, Freyr was also venerated across the realms as a symbol of fertility, having taken over a hundred wives and fathering thousands of children.

Aesir-Vanir War
During the Aesir-Vanir War, Freyr was chosen to be the High Chieftain of the Vanir army. Despite having fewer men, inferior weapons and armor, and less organization than the Aesir, under Freyr's leadership, the Vanir proved a formidable opponent to the Aesir. During the war, Freyr was so fearsome with his sword that the Aesir rumored that the sword was enchanted to fight for him, with the aim of discrediting their foe's combat prowess.

After much bloodshed, Freyr and Odin called a truce, which ended the war, with Odin marrying Freya, and Freyr staying in Asgard as a hostage. While in Asgard, Freyr's legendary sword was stolen by his messenger Skírnir. The Aesir mockingly rumored that he gave up his sword to woo his wife Gerðr, similar to the rumors about his sword fighting on its own. To replace his stolen sword, Freyr took up an antler from a Dale Stag and fashioned it into a battleaxe.

War of Alignment
During the War of Alignment, Freyr joined the war council of the Alliance of the Hawk, headed by King Odin. In the battle of Vigrid, Freyr engaged in single combat with the fire giant Surtr, where he shattered Surtr's flaming sword, but was burned severely in doing so. Knowing he would not survive his injuries, Freyr tackled Surtr off a cliffside, where they both fell to their death.
