Blades at Dawn
Forgotten Goddess brought back to life to claim her revenge against the other Gods.
Nightchill is simply a mystery to mortals. A minor Goddess of the Night and Darkness, she befriended the primordial Nero and became something akin to a lover if those words can be applied to alien entities. Betrayed by an angel under her service at the beginning of the Dawn War, she was tortured beyond madness by arcane means to use her divine essence into powering an arcane weapon designed by the artificer Gond, and take the mighty Nero down.
Her remains were dumped in the mortal realms to be forgotten but she did not dissappear into oblivion. Now in possession of a new body she watches her vengeance unfold.
