The Gren are a small Mechanical Race built for silence and quick thinking. Their processors are unmatched at quickly finding the path of least resistance, though this tends to make them quick to act instead of thinking of the long term consequences. Their processesors are well foiled by those of the Baykon. The Gren are tiny humanoid in appearance, usually only reaching up to a grown mans thigh. Their feet and knees though are replaced with small wheels so that when they kneel, they can move around on wheels. These wheels are special in that they can drive along nearly all surfaces, including walls and ceilings. As such, they are masters of infiltration. In Krehftan Mythology they are said to have been created by The Builder but their purpose for being made is unclear.
