The Wild Hunt

The Wild Hunt is an otherworldly phenomenon that occurs across Coryphiel. It is a host of Denizens upon unearthly steeds, which ride across the world and between realms. They are wildly unpredictable and have unknown motivations. Sometimes they kidnap wandering humans, and other times they kill indiscriminately.
In legend and folk tales, the Wild Hunt portends doom and destruction. They are said to appear as a harbinger of great death, and this may have some measure of truth to it. Often their sightings are followed by some of the largest wars, famines, and plagues in history. 
The numbers recorded for the Wild Hunt vary. Sightings describe seeing between seven to twenty riders. Likely, this is due to exaggeration, but researchers also suggest that not all the Hunters go on each hunt, or that there are multiple groups of hunters. This is supported by the fact that descriptions of the leader of the hunt do not match up. Some reports describe them as having horns and four arms, others describe a many-eyed creature wielding a bow and arrow.
The Wild Hunt are always describes as being heavily clothed and covered, with glowing blue eyes peeking out beneath their veils and hoods. This, more than anything, proves that the Wild Hunt are Denizens of the Otherworld.
The steeds of the Wild Hunt are usually similar. The pieces of their skin that can be seen are shadowy, and their eyes glow. The Wild Hunt also have hounds which are the same as this. These creatures come from the Otherworld, much like Denizens, and are probably created by the Wild Hunt.
==== Encounters ====
In all of history, the Wild Hunt have spoken to very few people. Lunothricus the Historian describes a brief encounter with the group:
"They sat around a great blue bonfire, but unlike men, there was no revelry or drinking at this event. Nearby their strange horses stood, without ropes to bind them, but not moving away from their riders. Upon spotting me, the huntsmen greeted me and bade me sit at their bonfire. Wisely, I turned around and fled"
The Shavhani mage, Tanira Zi'Dao, supposedly stopped the Wild Hunt in their tracks as they rode through the mounains, and had a long conversation with them. Unfortunately, the accounts of that conversation are locked away within the library of Mika'Zah.
