I made 36 character concepts, and I'm now certain it is possible to make a large scale cast using the face generator. L.L. sprites are flexible enough to get the job done for almost any face, so I think I'm going to begin developing the setting and plot so I can get busy fleshing out and finalizing character concepts.
A new concept I've put some development into. One of the last living Blood Elves. Her species were wiped out as a result of their uncontrollable blood lust and appetite for violence. It always lead to war, and they destroyed themselves fighting humans, other elves, and each other. 300 years ago, human kingdoms launched a campaign to destroy the last of their decaying empire, and a culling of the species began, turning into a genocide over time. Nevara was raised among Elves and taught to control her temperament, but she was never able to adjust to the lifestyle of a 'normal' Elf. She constantly rebelled or lost control and got into trouble. As a young woman, she ran away to separate herself from other people in order to protect them.
