Just a regular sword and sorcery fantasy RPG in a Tolkienish setting... except the sacred quest of the hero is long over and the dark lord was defeated decades ago. Now the humans, elves and whathaveyou rule the land and all the remaining descendets of the "evil" goblins and orcs are enslaved by them, while the former hero rules the realm with an iron fist. You play a lowly slave who escapes and now tries to rally his people to fight his human slavemasters and free his people.
The jist: As a token evil henchman, you're an awful lot smaller and weaker than even the lowest human enemies so leveling up is paired with learning and/or developing more strategies to make up for your disadvantage.
There are two possible outcomes to your quest: You overthrow the old hero of legend and history repeats itself, just with the roles reversed, or you try to lead all the races to a peaceful coexistance, depending on your final karma level and dialogue options, sidequests ect. you take throughout the game.
