The Arceans aren't evil, but they are not completely good either: while they care about honor, they also take pride that they are the physically toughest race in the galaxy, standing 12 feet tall. Because of their stature, the Arceans want to conquer and control the galaxy. Naturally this puts them at odds with some of the other militaristic civilizations such as the Drengin Empire, whom they despise (though pretty much everyone at least fears the Drengin).
