Okay, so I have this big sexy hook for my D&D story, and I want to know if there is a way that I can do this while still following the rules.
The history for this is that 100 years ago in my campaign's past, there was a powerful wizard named Egan. He ruled over a group of pure evil named The Black Hand, and was stopped in the past by the five glorious heroes (my party's old heroes).
I want Egan to make a return as a form of lich. Is there a possible way? I would base it around the idea that some of the descendants of the original Black Hand were trying to bring the 100-year-old corpse of their former leader back to life in a form of ritual or other legal mechanism.
The group that is attempting this is level 8, with a few members at level 10. However, they have enough gold/resources to be able to fund anything they require that they don't currently have. Egan was not originally a lich, but I would like to see if there is a way to bring him back and then turn him into a lich.
