In 2784, three days after Kerensky's legendary exodus, Jerome Blake had reestablished the Prime, or First Circuit of the former SLCOMNET. The planets of New Earth, Barnard, Alpha C, Bryant, Procyon, and Dieron became the new First Circuit. By the late 2850's, ComStar's efforts to strengthen and expand the vast communications network had succeeded too well. Increased communications had dramatically slowed transmission time. To decrease the load, Primus Karpov increased the First Circuit to ten stations in 2857. The newest members were Precentors Arcturus, Oriente, Altair, and Capella.

The Primus makes all decisions, which can be overridden by a majority vote of the First Circuit. The Primus can also be removed by a unanimous vote of the First Circuit. Since the Primus votes in all decisions, removal is very unlikely. Currently, Sharilar Mori serves as the Primus, with the First Circuit being composed of Precentors New Earth, Sirius, Bryant, Dieron, Procyon, Caph, Barnard, and Alpha C.

Precentor Atreus Demona Aziz is still officially a member of the First Circuit, but due to her involvement in the Toyama sect of the Word of Blake splinter group, she does not attend meetings or vote on matters.

The ComStar command hierarchy underwent great changes in the Reformation. For nearly 300 years, under the leadership of the primacy, the First Circuit held sole responsibility for administrating the ComStar communications network. The ranking Precentors of the First Circuit maintained ComStar's religious status among the citizens and turned the writings of Jerome Blake into gospel.

In the new Order, the First Circuit can no longer function simply as the cloistered leaders of a quasi-religion. The Precentors must often travel far from the marble halls of Hilton Head to serve as much-needed administrators, diplomats, and ComStar liaisons.

For centuries, misguided leaders of ComStar used the communications network and their exclusive control of the technology to manipulate events in the Inner Sphere to their own ends. A particularly costly abuse of this power occurred during the Clan war, when Capellan Chancellor Romano Liao used interstellar communications to send assassins against Justin Allard, husband of the St. Ives Compact's Duchess Candace Liao. The First Circuit knew the content of her communications but failed to prevent her instructions from being carried out. The Inner Sphere lost a valuable life through their inaction.

ComStar's new policy of openness extends to the First Circuit's administration of all communications. The Free Worlds League has unfortunately chosen not to benefit from the new democracy in ComStar, and though the First Circuit maintains the seat of Precentor Atreus, representative of the League, that Precentor has not appeared at any meetings since Primus Mori took office.
