He is a god to the Gargoyle people and the embodiment of their principle of diligence. He is merciless and evil... neither demon nor machine but a hybrid of both, Exodus is the spawn of Mondain and Minax, the arch-evils of the first two Ages of Darkness in Sosaria. From Ultima 3 comes this classic villain's portrait for use with any worthy enough balrog or demon to bear his likeness. ;)
Side Note:
With my new portait utility, all my new portraits come out perfectly, and work well in-game. No more upside-down pics! To celebrate, I've created Exodus from a pic I found on the Web which had been originally from the cover of the game box for the PC version of Ultima 3. I imagine this will be useful to anyone remaking classic Ultima games for Nwn, or just Ultima fans in general. Cheers!
