On cloudy nights, a large, foreboding figure can be seen floating through the clouds. For those with keen hearing (Listen 30+), the sounds of heavy beating wings can be heard, albeit slowly. It's as if whatever is flying is absolutely massive. No matter who tries to see past the clouds, they are unable to make out the figure.
What is known is that as this beast causes a chilling stillness near the areas it flies over. For those with Detect Undead, they would know that whatever this beast is, it is definitely one no longer from the world of the living.
It flies around the forests of Cormathor, particularly near the Forest of the Dead, causing the residents there to become restless and more aggressive than normal.
