newmonster   "Umbral"
descr        "The Pale Ones seem to be accomplished Necromancers as well as masters of elemental magic.  The dark spirits of the ancient dead have been encountered on several occasions.  Worst of these abominations are the Umbrals, huge spectres resembling Ancient Pale Ones with prolonged faces ending in sucking mouths.  It is not known if the spirits of dead Pale Ones grow like the living ones, or if the larger Umbrals are the spirits or memories of ancient ones.  To date there are no records of magically adept Umbrals, so there might be some truth to the Dwarven claims that only weak souls that are easily corrupted return as Umbrals.  Dwarven lore also suggests that there is a Cavern of Deeper Shadow somewhere, a dread place where Umbrals reign."
