Ghost Town

Long, long time ago this town had been an outpost of the Good races. The town was wealthy and propered. As it is located in the far southeastern corner of the wastelands, right beside the street leading from the orcish caves to the north, strong defenses allowed the town to push back the attacks of the Dark
Armies.
But then the Human Necromancer Xantharus arrived and plotted evil plans. At night he sneak through the town, killing people and raised them as undead zombies. The inhabitants of the city wondered about the vanishing of all their people, but could not explain it. Then, as Xantharus army had been strong enough, he stormed the city, killing everything that was alive.
Intrigued by his victim and now thinking himself the most powerful of all Necromancers, the opened a gate to the lower planes. But then the unexpected happened ! Through the gate stepped an avatar of Orcus. Xantharus fought a fierce battle to dismiss the avatar, but the fight was lost the moment it begun. Xantharus barely escaped the avatar, and noone had seem him thereafter.
But the avatar summoned more of undeads, and even some tanar’ri. He created an outpost of the lower planes in the town. More and more undead and demons arrived and are still arriving.
