Can we please not reduce the plot of this amazing project into "Super Devil wants to dominate the world and creates an eternal dictatorship and we have to stop them"?
I have great rejection to plots based on shallow "good vs. evil" line. Maybe it is my history major, summed up with the reading of my old dusty books from AD&D, stuff like Complete Book of Villains, Dungeon Master Guide, specially the part of story creation and motivation, or my many years of DM-ing... well, i just don't like to be caught into moral presumptions of a eternal battle of good vs. evil.
It is very annoying to reduce the rich world of possibilities and motivations to "stop the Super Devil" storyline. These are for kids...
I want my character dragged into political assassinations, dethrone of legitimate kings, favors in exchange of land, nobles unwilling to accept the new regent while the true king is too young, or priests fighting over the control of the richest church around; a rich businessman that lost his horses to a local arrogant noble and has no one to appeal since the local courts are all nobles in favor of that arrogant prick...
The universe of possibilities is tremendous, so, please, do not reduce the plot into a "good vs. evil" shallow.
