Pax Cybertronia

The Pax Cybertronia was the unilateral peace accord signed after the Decepticons lost the Great War. It places the Decepticons (and later their descendants the Predacons) at great disadvantage.

Leading up to the Beast Era, powerful factions within the Predacon Alliance such as the Tripredacus Council want to continue to build up their resources under the restrictions placed on them by the Pax Cybertronia before a new campaign of conquest. This is a major point of contention between the leadership of the Alliance and sub-factions that would prefer action today.
