The Segben is similar in appearance to a hornless goat, with glowing eyes and large ears. It exudes a sickening charnel smell which requires any character coming with 5 feet of the beast to save vs. poison or attack at -1 for 2-8 turns through nauseas.
Segben are destroyed by sunlight, and generally hide in the darkest recesses of the forest until dusk, when they appear under the floor of a house where someone lies gravely ill or dying. They can sense the smell of death at a distance of up to a mile, and will seize any opportunity to make off with an unguarded corpse. They are not known to frequent graveyards, however, apparently preferring to move in immediately after death.
If surprised in their feast Segben will usually flee, fighting only if cornered or if the odds are heavily in their favour. They can attack by lashing out with their small forehooves, but their most feared attack is their bite--if they successfully bite any victim, or even its shadow, the victim must make a System Shock roll or die immediately.
Although they have a number of ghoulish characteristics, Segben are not undead and are not affected by holy symbols or the like.
