Lord Banister

From ROI Wiki

Lord Banister is a 8th generation descendant of racers who first arrived on the planet of Offworld several centuries earlier and eventually formed what would later become the Sheffield Republic. He and his family have a morbid fear and hatred of all racers, and have given a standing order to all within their republic to exterminate on sight any that they find. They are one of the Four Kingdoms and are the south eastern most of the four. They are also bitter rivals with the Thorn Confederacy and the Unity Empire.

They are neutrally at odds with the Gak Republic as they don't share a common border with them, even though they are near neighbors. He and Lady Lidia, his wife, initially rescued Trevor and Birash after the sinking of their ship, but then attempted to have them killed once it was discovered who and what they really were. It's his efforts to destroy Simon's team, along with the Unity Empire, that eventually lead to the destruction of his republic, and the rest of the Four Kingdoms by the controllers.
