Shade

From HammerWiki

While most of the Dark Elf folk live in the security of the fortified cities - one of the clans, the Shades of the Blackspine Mountains, is a notable exception. The Shades are a silent and deadly brotherhood of warriors who guard the mountain passes to the west. They live apart from the rest of Dark Elf society, waging an endless war against the enemies of Malekith.
