Warning: The following text contains spoilers relating to the plot of Nightfall.
Kormir, the Goddess of Truth is the immortal incarnation of Kormir, the former Spearmarshal of the Order of the Sunspears. After having defeated the fallen god Abaddon, Kormir absorbed the divine power that was released, sacrificing herself, and thereby became an immortal god, taking over from Abaddon the powers of the God of Knowledge and Truth.
And so it came to pass that Spearmarshal Kormir, hero of all Elona, was pulled into the inky blackness surrounding the God of Secrets. And though her sight had been robbed, her body wracked, and her spirit flayed, she remained resolute.
And so was she joined within the Realm of Torment by fearless allies, <name> and other great heroes, who stood at her side as she sought to thwart Nightfall. Together did they battle through Fear, and Anguish, and Madness, until at last they stood before the face of the imprisoned god; he who had challenged the Five and lost; he who threatened to break the chains placed upon him by the other gods; he who now sought to bring Nightfall to the world: the dark god, Abaddon.
And so did Kormir and her allies engage the dark god in titanic battle. And through her power, and their combined skill and bravery, and the blessings of the Five True Gods, did Abaddon at last face his ultimate defeat.
Yet the power of a god cannot be destroyed, and Kormir, making a choice that only a mortal could make, did take upon herself the mantle of the Goddess of Truth, with all its power and responsibility, all its dominion and duties.
And so by mortal hands did a new immortal enter creation.
-- Scriptures of Kormir, 1075 AE
Statues of the Goddess of Truth can be found in the Throne of Secrets and in the Chantry of Secrets. Kneeling at the statue in the Throne of Secrets summons the Avatar of Kormir, while kneeling at the statue in the Chantry of Secrets summons the Seer of Truth, regardless of whether or not the world has favor.
Another statue of Kormir can be seen in Turai's Procession during the Nightfall campaign's epilogue cinematic. In the 2007 Dragon Festival Emperor Kisu prayed to Kormir.
