Asgard

Asgard, known in Old Norse as Asgardr, was one of the Nine Realms of the World Tree and the home of the Aesir gods, from where they watched over the other eight realms. High in the crown of Yggdrasil, it was ruled since time immemorial by the All-Father Odin from his hall, and it was the final home of the bravest fallen warriors of Midgard, to which it remained connected by the burning rainbow bridge of the Bifrost. Traditionally associated with knowledge, war, and power, Asgard was nonetheless promised certain doom at the hands of the Jotnar at the time of Ragnarok, a fear that drove the Asgardians to turn their homeland into a fortress and to wage a ruthless campaign of conquest against the other realms. (God of War Ragnarök)

Government and the rule of Odin#

Though All-Father was a self-appointed title, Odin held enough charisma, authority, and power to rule both the Norse pantheon and the Nine Realms as a whole. He preferred to work behind the scenes, letting his henchmen do his bidding while he focused on gathering ever more knowledge. The burden of power and his fear of a prophesied demise made him increasingly greedy and paranoid, to the point where he did not hesitate to sacrifice even his closest followers. Prominent gods such as Tyr, Sif, and even Thor would ultimately turn on him, with dire consequences. (God of War Ragnarök)

Odin ruled through fear and information. With his ravens Huginn and Muninn as spies, he could be virtually everywhere at once and knew everything. He proved a pragmatic ruler when it suited him, ending the war with Vanaheim through his marriage to Freya and establishing total economic and political control over Svartalfheim with the help of Mimir, securing an endless supply of dwarven weapons and materials. Ultimately he ruled for the sake of his own power, not for his people or the realms. (God of War Ragnarök)

Military and the Einherjar#

The bulk of Asgard's army was the Einherjar, the fallen warriors of Midgard. After death in battle they were brought to Valhalla by the Valkyries, and upon receiving the All-Father's blessing they became bound to Odin and Asgard until Ragnarok. They did not spend their afterlife feasting; their purpose was to train endlessly in preparation for the final battle, instructed by the Valkyries in advanced combat and the use of the Bifrost. Their structure was rigidly hierarchical, each warrior specialized as a captain, archer, or thief. Their greatest strength was their ability to respawn in Valhalla whenever they were killed again, meaning Odin never ran out of reinforcements. Many Einherjar patrolled key areas throughout the Nine Realms. (God of War Ragnarök)

Geography and the wall of Hrimthur#

Asgard was a green and steep highland world surrounded by snow-capped mountains and crossed by vast expanses of water, with uninhabited plains called the Plains of Ida. Unaffected by the Fimbulwinter that ravaged Midgard, it was far safer and lusher than any of the other eight. The enormous wall dominated it, a raw rocky belt studded with giant rusted nails driven into the rock long ago by the giant Hrimthur. The wall protected the hall of Gladsheim and was considered impregnable, with a single hidden weakness known as Hrimthur's Flaw, concealed behind Asgard's Realm Tower. (God of War Ragnarök)

Within the wall lay Gladsheim, a settlement built in the Viking style rather than as a grand palace, which suited the humble image Odin had calculated for himself. The Great Lodge stood at the middle of it, home of the All-Father, his ravens, and the other Aesir, and beneath it lay the Rift, the source of Odin's obsession with knowledge. Nearby were the pub called Black Thunder, training grounds for the Einherjar, and the field of Vigridr, foretold to host the final battle. Many refugees from Midgard, seemingly brought there by Odin himself, had settled in the shadow of the wall, though Heimdall kept mortals out of the hall within. (God of War Ragnarök)

The mask and the invitation of Atreus#

While Kratos and Thor brawled on the frozen Lake of Nine, Odin invited Atreus into Asgard. Haunted by the prophecy of his father's death and frustrated by his inability to find answers, the young Jotunn eventually went, following Odin's raven Huginn. He was met first by Heimdall, the Bearer of Gjallarhorn, who toyed with him and read his mind before bringing him before the Great Lodge, where Thor and then Odin intervened. The All-Father adopted a benevolent manner, gave Atreus a room in Gladsheim, and presented him with what he called a major learning opportunity. (God of War Ragnarök)

Beneath the Great Lodge, in the Rift, a strange green light had appeared after Odin slew the first giant Ymir long ago. It shared a connection with a wooden mask whose pieces were scattered across the realms, inscribed in an ancient language Odin could not decipher. Believing Atreus gifted in forgotten tongues, Odin enlisted him to complete the mask, dangling the promise that it might reveal a way to save his father. The search took Atreus to Muspelheim, Helheim, and Niflheim, but the expeditions brought disaster, including the freeing of the great wolf Garm, and Atreus ultimately kept the completed mask for himself. (God of War Ragnarök)

Ragnarok and the fall of Asgard#

As Ragnarok approached, the Asgardians dug trenches and installed dwarven war machines around Hrimthur's Flaw, with the Einherjar under Queen Gna forming the bulk of the host and the Midgardian refugees pressed into piloting the machines. But it was not Heimdall who sounded Gjallarhorn as prophesied; it was Kratos, blowing the horn in Tyr's Temple. Odin's seal on the realms broke, and the armies of Alfheim, Helheim, and Vanaheim poured onto the plains of Asgard alongside Kratos, Atreus, Freya, Freyr, and the giants Fenrir, Angrboda, and Jormungandr. (God of War Ragnarök)

The wall was breached when Sindri exploited Hrimthur's Flaw and Atreus shot it open. In the devastated Gladsheim, Kratos spared Thor after defeating him a second time, and in fury at his son's disobedience Odin impaled Thor with his spear. Kratos, Atreus, and Freya then faced the All-Father himself, who proved a phenomenally deadly foe until their combined strength brought him to his knees. Atreus captured Odin's soul in a marble, but the vengeful dwarf Sindri shattered the stone, killing Odin for good in retribution for the death of his brother Brok. (God of War Ragnarök)

Aftermath#

Asgard's fate was sealed when Surtr, transformed into the primordial Ragnarok, shattered the wall and plunged his sword into Asgard's crust, killing himself and Freyr in a cataclysmic explosion. It imploded, the only one of the Nine that did not survive. Its destruction shook Yggdrasil to its roots, and its burning remains, the Remnants of Asgard, fell across the other eight realms. Odin's death and the ruin that followed broke the power of the Aesir, freeing the other realms after centuries of domination. The Valkyrie Queen Gna claimed leadership over the Remnants, while the surviving Asgardians who rejected Odin's ways followed Sif to a new home in Vanaheim. (God of War Ragnarök)
