There are 3 problems i see with resurecting the draketooths
The first, and most obvious, is they seem to be a lawful evil organization. Chaotic stupid illusionists dont exist, as illusion requires an ordered mind. Lawful does not mean rational, and a wizard's low wisdom wouldnt exactly serve them well for judging allies or tollerating outsiders.
2nd: Familicide is an epic spell, and the actual caster never died, just splintered out of V. Rich hasnt made a detailed description of the spell, specifically for the reason so that we dont know how bad it is. The spell might never have ended, while i suspect that Familicide is a permanent spell.
3rd: Thor isnt on speaking terms with the other hierarchies, i remember at one point in the comic, Celestial tiger chews him out for giving durkon some spells. Simply put, although Durkon has a few spells he can spontaineously cast, he isnt allowed full divine might, because its only what Thor can slip our dehydrated dwarf.
As for predictions:
V for Varsuvius. V is amnesiatic and has subbed his levels of Wizard for Ranger. He Dualwields throwing Sabers. oh, and hes evil. Blackwing is still his companion.
