Beneath the Planet of the Elves

Every elf or dwarf is aware of the horrors that lurk in the underground ruins of the long dead race of Man: crawling things with superstitiously shunned names, lurching things with nigh unpronounceable names, and oozing things left fearfully unnamed. But none of those evoke more horror than the Cult of the Dread God.

The cultists are utterly subterranean, emerging only briefly at night.  They resemble elves or dwarves, for the most part, except that they are taller and their features (when they are seen) are coarse and with an unhealthy waxiness.  They all dress in the vestments of their order and reveal little more than their faces.

The cultists possess powers of the mind allowing them to stun or control even the most strongly willed elf or dwarf.  They march their victims, puppet-like to their own sacrifice--for that is what the cultists seek when they emerge from their underground temples or monasteries.  Little is known of their hungry god other than his name--which is not commonly spoken for fear of drawing his attention--and that name is Ba’am. No elf has seem the god or his altar and lived.

There are adventurers' tales that suggest their waxy countenances are not the true faces of the cultists, but merely masks.  Whatever they were before, their god has changed them in strange ways. Tales speak of glimpses of bruise-colored tendrils writhing beneath their masks and uncovered heads, hairless and rugous, pulsing with malevolent intelligence.
