The Conglomerate

The Conglomerate was an Earth-based intergalactic corporation, a business empire and a self-perpetuating causal loop created by Cuthbert, himself a self-perpetuating causal loop. It was responsible for providing healthcare, education, and infrastructure, creating trade treaties that prevented intergalactic wars. The Black Guardian explained that the Conglomerate was so entangled in galactic events, its removal from history would cause inestimable chaos and tear the balance of reality apart.
