These tiny, vaguely humanoid creatures are animated accumulations of tomb litter - shards of bone, lone teeth, matted hair, bits of shattered tombstone, and grave dirt.

Tomb motes sometimes spontaneously arise in graveyards with a high concentration of buried magic, undead activity, and/or mass burials. As accumulations of grave detritus, tomb motes are surprisingly smart and vicious.

Tomb motes weigh 5 to 8 pounds and measure no more than 1 foot in height.

Tomb motes understand Common and Abyssal but do not speak.
