I remember one story about how a supposedly good wizard discovered a method of becoming a lich that required far less human sacrifices than the one he knew about previously. This different method however required he use innocent children. So he found the sickest children in the village and took them claiming he was going to try to heal them. But the few children he took weren’t enough but he could feel the power working. So he poisoned the well just enough to affect the younger, weaker children, and took them. But again it wasn’t enough… Once he finally became a lich, the town he wanted to protect with his immortality and new-found power, was empty. All used in his ritual.
Oh right, not Halloween yet, I’ll have to come up with a new Halloween story for later! Have a great weekend!
