Scoured Iron Mine is a Vampire Counts resource building in Total War: Warhammer. Cursed iron ore is laced with warpstone. Such mines are prized.
Background
A scoured iron mine is one where such a seam of cursed iron is discovered. Only the Undead can mine this, for mortals will be mutated by the iron within. The ore is priceless, sought by Necromancers from across the world to fuel the darkest experiments. There are also other creatures that crave such material - red eyed and be-tailed, but we do not talk about them...
