Coldharbour is a realm of Oblivion created and ruled over by Molag Bal, the Daedric Prince of Domination. The realm reportedly contains an apocalyptic version of Nirn: the sky is on fire, the ground is a barely-traversable sludge, and ancient, blackened ruins fill the landscape, including a defiled copy of the White-Gold Tower. It is unnaturally cold, even with magical resistance. Even the air assaults the senses, changing rapidly from rancid death to sweet flowered perfume. As opposed to other realms of Oblivion, Coldharbour is largely lifeless, instead filled with souls of the dead, called Soul Shriven, where they are tormented for eternity.
Sotha Sil journeyed to Coldharbour in 1E 2920 to bargain with Molag Bal. The mage Morian Zenas famously visited the realm during his voyages through Oblivion, and wept at the sight of the desolation. In 2E 579, as the Interregnum dragged on and the Dragonfires remained unlit, Molag Bal's minion Mannimarco deceived Emperor Varen Aquilarios into initiating a ritual that triggered the Soulburst. The ancient covenant between mortals and Akatosh was broken, and Nirn was set adrift in Oblivion, rendering it vulnerable to Daedric incursions. Molag Bal began deploying machines known as Dark Anchors to pull Nirn into Coldharbour, and sought to merge the two realms into one through a process known as the Planemeld.
A female Vampire Lord of pure blood, who has been gifted vampirism directly by Molag Bal, is known as a Daughter of Coldharbour. In a speech to the Champion of Cyrodiil, Mankar Camoran incorrectly names Meridia's realm Coldharbour.
