Bleakstones

Bleakstones are earth-aspected elemental Blights. They pervert the normal function of the earth - to nurture life upon it - by draining vitality out of anything in contact with the ground they’ve melded with. As such, they are particularly deadly to plantlife, though animals who remain on such earth will also wither and die.
Bleakstones appear to be large masses of rocky protrusions bound together by greyish soil. They do not seem to have any sensory organs. They have the ability to meld with the ground and drain anything in contact with it in a small area.
