Oket, Herald of Darkness

Oket speaks in fluid tones and sings with the voice of angels, but her heart is foul and treacherous.   Indeed, Oket can take on another appearance entirely, disappearing into insubstantial shadows and unveiling an evil majestic form that leaves those who see her shaken and weak—and often blind. Speaking of this form is difficult, but poets and bards trying to describe it have said it resembles an apocalyptic horror built of chained souls and the slow death of children carried along in a glacial river, rushing to an inevitable doom.
The black sword and star-scattered cloak of Oket is part of its magical substance and cannot be parted from it. Some believe the cloak and blade are true visions of her body; the smiling face and pleasing form are entirely illusory.
The heralds of darkness are companions and sometimes masters to the shadow fey. They seek to draw many others into their orbit with wild promises of great power, debauchery, and other delights. They are rivals to the heralds of blood and bitter foes to all angels of light.
