Would a Wizard who went through with this ritual - and survived - go 'mad with power'?
Do you think he would stick around a large city? Maybe claim part of it as his domain?
Other than hunting down his old enemies to destroy them, what might motivate this type of power mad wizard?
I'm think of a "white court wizard" that got his hands on an 'outsider' type tomb that listed the ritual, and he decided, why not - become a demi-god (sort of), went through with it, lost most of his humanity (he did kill 1000+ people) as part of this ritual. Do you think he'd stick around?
If my group can't take him down in 30 days, I'm thinking of making him an ongoing pain-in-their-backside kind of guy - hindering them behind the scenes becasue they tried to take him down in his first 30 days?
Any thoughts? BTW - thanks for the input thus far, I really appreciate it.
