Lex Primus

“Here, even silence has form. Even thought must submit to precedent.”

•  Conclave Archivist Yulean Strass

In the center of the Cerebrant Domain, nestled within the Lex Mantle, lies Lex Primus, the Cortex capital planet. It is the cradle of the Echelon Code and seat of the High Conclave. This coreworld carries both governance and tradition, it is where Mantle Trials are held, where the most contentious decisions are issued, including the binding of the Covenant’s AI resurrection efforts after the OT-3907 Schism. The Mantleguard maintain an overwhelming presence on Lex Primus, acting as stewards and guardians.

​

Despite its authority, Lex Primus is vulnerable. Armada Gene Dynasties refer to it as “The Hollow Stone”, a target untouched during the Severance War, but ripe for reckoning. Cortex records show multiple Armada infiltration attempts in OT-3918, all intercepted by the Bellum Order.
