Hi I am looking for information on an old monster from Dragon mag. I don't know the name I just know the special features of the monster. This monster eats the essence of undead and admits a aura that attracts them in swarms. I think the entry said something about placing it in a town and have the PCs try to find the reason undead were attacking the town. If anyone knows what this monster is please let me know. It has been driving me nuts. I want to use it in a campaign I am running. Thank you!
