The Freezing Wraith
A shimmering figure of blue mist. The Winterghast is a powerful spirit of cold. Wherever the Winterghast passes, frost trails behind. The spirit absorbs the heat of wherever it passes, but never warms, simply spreading more and more cold.
The Wintergahst stalking along the Umbral is a testament to the fact that few things go as well together as the dark and the cold.
Beneath the mystery of its blue, cold, light the Winterghast is a potent intelligence. It can reach into the minds of mortals, taking from them even the thought of warmth. It has immense experience with the minds of mortals, and what they will do when the cold drives them to desperation.
