The Code — the unwritten rules of engagement that dictate supers should avoid killing or maiming each other, or targeting non-super individuals such as family members. Gratuitous violence leads to escalation, which in turn would be eventually stamped out by the cabals of supers that govern their own kind. For example, a psychic seeking to influence a government election would eventually be found out and taken down by the Menagerie, a hive-mind of powerful psychics that eats their own. Each of these cabals worries that any undo flex of their power would result in the banding together of other supers to take-down or exterminate them. Each cabal has a hand in maintaining the current stalemate of world powers and powerful corporations. Similar principles to nuclear Mutually Assured Destruction. 

The Vault — A prison for supers

The Menagerie — A cabal hive-mind of powerful psychics
