Devils, however, are Lawful and I get the feeling from what you wrote about them in ther MM and MM II that their hierarchical organization would frown on such independence (to say the least). Would an undertaking such as having Dispater's followers on the Prime Material plane launch an attack on a religious order of good need to be OK'ed by Asmodeus, for example, or, since he's an Arch-Devil would something like this be left to his own devices (unless, of course, it met with serious problems or failure)? Also, since Dispater is, according to the MM II, an ally of Mephistopheles, do you have any thoughts on how that dynamic would play out?
