Bintity

Bintities are a type of civilization that is superior to Untity and inferior to Trintity. They are currently a Type 3.5 Civilization, so have colonized their whole galaxy group. The bintities is soon planning to colonize Supercluster and achieve K4 status within a century. Also, the bintities have been fully united and only minor wars happen.

Trade
Bintites barter with Untities and Zerities for mining resources, Dyson swarm material, and other goods. Without this help, it is likely that they would remain stagnating at Kardashev 3.
