I'm interested in running a solo game for a villainous character. Ideally the successful applicant will start out at the beginning of his/her villainous career, and the game would revolve around the villain perusing his/her goals.
The game for the villain won't be a linear campaign, rather it will be handled in the form of Acts (critical periods of time in the villains history), focussing on his/her rise to power.
Once the villain is 'established' I will DM a game of heroes, who will stumble upon the machinations of the villain and attempt to thwart it. The heroes will start out at a lower level to the villain, and it won't be until they reach upper levels, that the prime focus of the heroes adventures will be to destroy/neutralise the villain.
This type of game would especially suit a monstrous type of villain, which is too underpowered to play with others PC's of the same level, due to ECL limitations. However, I'm seriously open to any suggestion.
And finally if the villain manages to create his/her own evil empire or attract minions and cohorts, then I would also be happy to open the door for evil PC's to part of these followers/minions.
In particular I'm interested in running a game for a well throughout villain, with a believably personality/background, focussed on pursing potentially world-shattering goals. I'm happy for the player (you) to have a better idea of the goals you want to pursue with your character, and allow the goals to evolve over time for the actual PC.
For instance you might want to play an Ogre Mage Wizard/Sorcerer who will eventually become a mighty warlord, who seeks to overthrow the weak human kingdoms, and establish a mighty monstrous empire.
However, the actually PC, may start out with a chip on his shoulder towards humans and other civilised races, and be interested in surviving and gaining a measure of power. Over time as the Ogre Mage gains more followers and power, it could then occur to him to try and carve out his own empire.
And finally it would be great (but not required) if the successful applicant would be willing to do a similiar type of adventure, for a villianous character of my own devising ;)
