Ostog the Unslain: OSTOG THE UNSLAIN cannot be killed - or at least that's what he keeps telling everyone (and himself). His heroic deeds keep the skalds of his northern home singing of his bravery.
Cairn Wight: The CAIRN WIGHT guards forlorn tombs and burial mounds. So deep is its undead evil that its very touch drains life - an ability that extends to its terrible sword.
