This is the royal court of the drow in Runfeld. The origins of its war with the Seelie Court are not remembered, though many are created in the tales of underhill. They felt themselves betrayed and wronged by their surface elvish cousins and swore revenge. This is the reason the Seelie Court was nomadic, for to stay in one place meant to be besieged by their dark kindred. When the Seelie Court established power over all the surface world, however, the Unseelie Court stopped warring in earnest and settled for menacing any Seelie elves who traveled alone.
The Unseelie Court claim that Rilian’s choice of Tara as capital was as the farthest place possible from their own court, short of taking ship. After Rilian relocated to Tara, his hold in Runfeld waned. The Unseelie Court holds sway there now. In practice, this only means a demand of tribute in the form of slaves and mead, and the Unseelie Court takes little interest in the doings of the surface world.
If a riocht fails to pay tribute, or if the Unseelie Court is too full of restless knights, it calls a Wild Hunt. The Hunt rides out at sunset with the intent of killing or capturing everyone in a riocht. It is a great honor to be named the Horned King, leader of a Wild Hunt.
