The Pax Byzantium Convergence is a War Sun and Destroyer specialist faction introduced in the Chromatic Frontier expansion. Masters of overwhelming capital ship power and ironic "peacekeeping" through military force, they are the only faction capable of fielding three War Suns simultaneously while building massive destroyer fleets to screen their advance.

10 Lore

Home System Concordia Byzantia
Planets Alta Pax (3/0) — The older and larger of the two worlds, its surface scarred by the war that preceded the Convergence and rebuilt entirely in the image of what came after — shipyards as far as any horizon.

Nova Pax (2/1) — A younger, partially terraformed world whose construction was completed by the Convergence itself, designed from the ground up as a logistics and supply world with no civilian districts and no unnecessary infrastructure.
Population ~14 billion Byzantians
Government Conclave
A council of War Sun commanders whose unanimous consent is required for any decision of consequence.
Disposition Implacable
Once the Convergence sets its terms, no force in the galaxy has ever changed them.
Tendency Objective
They do not seek to rule the galaxy — only to hold enough of it that no one else can.
The Monopoly on War

The Pax Byzantium Convergence was born from the aftermath of a war so catastrophic that its name has been deliberately erased from their historical record. What survived — barely — was a coalition of military commanders who had watched their civilization nearly consume itself, and who drew from that experience a single, absolute conclusion: peace is not a natural state. It must be enforced. Alta Pax and Nova Pax were rebuilt not as centers of culture or commerce but as shipyards, their entire industrial output redirected toward the construction of the most powerful instruments of deterrence the galaxy had ever seen.

The Conclave that governs them meets rarely and speaks seldom. Each member commands a War Sun, and each War Sun represents a veto — no decision of consequence can be made without unanimity, a system designed specifically to prevent any single commander from repeating the mistakes of the war that created them. To outside observers, the Convergence appears monolithic and slow. To those who have negotiated with them, they appear immovable. Both impressions are correct. They do not want territory, they do not want tribute, and they do not want influence. They want the galaxy to remain calm, and they have built enough firepower to make that preference everyone else's problem.

The Byzantians

The Byzantians are old, and it shows. They are tall, heavily built humanoids with a slightly asymmetrical bilateral structure that suggests an evolutionary history of redundancy — two hearts, paired lung clusters, backup neural ganglia. Skin tones run purple-grey to deep violet, often darkening with age into near-charcoal at the extremities. Their faces carry a characteristic gravity of expression: the muscles around the mouth and eyes are extremely well-developed, suggesting a species whose emotional communication is far more precise and nuanced than their reputation for silence implies. They dress in formal military architecture — layered, structured, with deliberate weight to fabric and clasp. Everything is muted purple, grey, and black. Nothing is decorative. The War Sun commanders who constitute their highest leadership are, almost universally, old, and they look it — worn in the way of things that have survived enormous forces by being dense enough that nothing could break them cleanly.
