I’ve never actually played a villain, or even an antagonist really. I tried to make one once long ago, with the idea of them possessing no tangible power (magic/martial skill), but rather influencing others towards an end that ultimately would be commendable, perhaps even, “Good,” but the methods of achieving it being bad.
It just never really panned out as within five minutes of rolling the character someone came up and killed him for being, “Bad.” That was a product of the times though. In the old days people just jumped on antagonists before they had a chance to even start rolling.
The concept itself was a peasant who’s ambition was to bring about great prosperity for Stormwind and her peoples. That was the long term goal which most would say is a good motivation, and it’s one he would have shared with people he’d try to rope into his plots. With the long-term goal in hand he’d focus on short-term goals to reach that, the first naturally being the acquisition of significant wealth. This would naturally begin with the most legitimate of methods; hard work and sweat. Those roped into his grandiose plans would, at that point, be made aware of the new short-term goal: actively fighting the threats of Stormwind.
Using that previously acquired wealth he’d arm and train people, and send them against the likes of Gnolls, Murlocs, Bandits, etc… The goal would be to earn a reputation, even if a fairly minor one. Such individuals would of course bring back the spoils of war, which would be re-invested to further increase the quality of equipment and training. At this time, however, two accounting books would come into play; one open to anyone, and one just belonging to this antagonist. That second one held a true account of the wealth garnered, with accounts being set aside for less legal transactions, mostly involving goblins.
Once a sizable influx of capital was established, and most major threats had been dealt with, he’d have started manufacturing false threats for his unaware heroes to tackle, with said threats themselves being as unaware as possible of his hand in it. At the same time, generous donations would be made to the beneficiaries; orphanages, schools, the poor, the church… and off the book, gifts would be sent to the proper members of nobility. In time the names of certain nobles would begin to be associated with the efforts of those heroes.
I’m sure you guys get the idea by now. A person wielding immense influence rather than power, working behind the scenes to manufacture suffering and need so that his heroes can answer the call. Someone who’d play different factions against one another (nobles and royals as an example), maintaining their only interest is the welfare and prosperity of the kingdom…
Typical political villain, basically, just one who starts out at the bottom and works his way up.
