The Revolutionary Groups are comprised of Primal Instinct, Renegade Regime, and SwiftClan. All three groups have set up societies completely separate from the traditional Clans of Classic -- Primal Instinct in the massive dark woods and city far away from the other Clans, Renegade Regime in tunnels under the Clan territories, and SwiftClan who never lives in the same territory for long. Thus, their cultures are totally different from the expected Clan hierarchy. Renegade Regime has formed a complex military structure centered around several underground posts, and while they are often misunderstood, they are not evil. Primal Instinct, on the other hand, is a ruthless groups of cats and do not welcome newcomers, marking their borders with the blood of the unfortunate souls who crossed them. SwiftClan is a very peaceful clan allowing others to roam their lands and are almost pacifists in nature.
