Just For Fun...

Swathed in blackened, rotted robes, it pushed itself clear of the tomb, the solid stone unravelling atom by atom and reshaping itself in a swirling black shroud. More and more of the stone disintegrated to form the concealing darkness of the creature. Soon all that was left was the slab of the tomb with the final piece of the metal burning brightly in its surface.

Uriel had a barely-perceived vision of a gaunt, mouldering face with twin pits of yellow glowing weakly from within. There was insanity and a raging, unquenchable thrist for suffering in those eyes. A cloak of ghostly darkness hid its true form, a pair of rotted, bandage-swathed arms, all that penetrated its nebulous outline. One limb ended in a long, grave-dirt encrusted talons, the other in what appeared to be a huge blade of unnatural darkness, angled like a vast scythe.

As the creature rose to tis full height, Uriel saw that it towered above the mortals beneath it; swirling eddies of darkness at its base snaking around the bodies of those not quick enough to escape its grasp.

The cloak of darkness swept two of the alien warriors up. The scythe arm flashed, passing through their armor and bodies with ease, and their withered corpses dropped, no more than shrivelled sacks of bone.
