The Sundering: Rise of the Witch King is a mod for Medieval 2: Kingdoms and based around the fantasy world of Game workshop's Warhammer universe during the civil war between the Elves, the mod's campaign opens with the Death of Bel Shanaar in -2751 IC.
Cold One Knights are the most fearsome of the Dark Elves' dreaded warriors. The skill of the knights and viciousness of their mounts set them above the cavalry of lesser races. Though few in number, the ferocity of the Cold One Knights is such a decisive weapon that they can win a hard-fought battle with a single devastating charge.
Looks like one tough bastard :P
