Depending on how advanced their society/lands are and how far along they are would be a couple of the subjects i need too factor in.
Because if you have a demon lord, who is well known and is actively ..let's say converting, villages too his cause, then he would be well known, if not feared by other lands, and hated by most demons. (i mean, i have an idea brewing too make it work, but that's just something i had too point out XD: )
That's actually all i can think about really, but i hope you don't mind if i think of other questions and what not.
I love questions actually, it helps strengthen the concept and helps it to fit the world. I'm sort of drawing inspiration, right now, from Sesshomaru, considering what this RPG is based off of-his role, not so much his personality. An enemy, or at least, antagonist, but not one without honor, and one with understandable motives.
Indeed, I'm considering that, perhaps what brought about his current position, his current role, is being treated for injuries, effectively helpless, by the monks of a certain sect. Whose beliefs he ends up adopting, or at least admiring. So the mention of conversion is quite fitting.
It also happens to fit excellently in Inuyasha tradition.
....
heck, could even make him a relation to the Demon Lord half of the pairing to complete the picture. :p
And yeah, I expect he would be feared-the Ikko-Ikki certainly didn't put the lords of the historical Japan at ease!
