Updated Mitchell ref! I really didn't change much for him-- since I've always drawn him with short grey hair the only thing that needed to be adjusted there was the underlying hue. He's now half Metzcualcatl on his father's side, though some people (read: Balthazar) still only refer to him by his Stelligan surname.
The Metzcualco Empire covers most of the equivalent-Americas, with a few treaties that allow colonies from other empires to exist (such as the Swathe of Avis established by the Stelliger Empery). While the lands closer to the capital generally remain stable, the farther out you go the more common it is for territories to shift in and out of empirical control, though this is usually a bloodless process. The Integritas movement that swept the southwest of the Swathe, particularly Greenmarsh, has destabilized the treaty created by the former Empress Avila, and Metzualco is moving to reabsorb control of the area in hopes of stopping the movement.
Edit: tweaked his skin tone a little bit more
