From publisher blurb: What's spookier than a ghost? A swarm of ghosts! From the pages of 10 All-New Undead Monsters comes the phantasmagoria. "A phantasmagoria is a whirling mass of more than 100 tiny ghostly entities. Each of these indistinct glowing orbs were originally full-fledged ghosts, but have since lost most their memories and power over centuries of unlife." And as an added bonus, this free monster includes instructions for crafting a phantasmagoria miniature. That's right, a free monster and a crafts project all in one!
