Sentinel-Commander Kedron

Kedron is a Prince-Prior and Knight-Commander of the Holy Terran Chantry, commanding its Sentinel fleet from the Argentine. He is a massive, bald, deathly pale man armored in full black adamant plate bearing the Sentinel order's eclipsed-sun insignia. His helmet is crowned with golden leaves identified by Hadrian as a Grass Crown, equal in prestige to the Imperial award. He wears the cathar's black muslin band across his eyes and carries a highmatter sword housed within his right gauntlet, which also projects electricity. His armor includes repulsors and wrist-mounted flare rockets.

During the campaign at Vorgossos, Kedron's bombing runs spread ionized particles to jam planetary communications, and he presses alongside Douro for Chantry access to Demiurge afterward. In the subsequent confrontation, Kedron boards Demiurge covertly -- bypassing all sensors and security through means unknown to the rest of the Imperial universe -- and suborns the ship's Crucible Beam to destroy the Latarran warship Hermetic Melancholia, killing forty thousand men, as leverage to force Hadrian's compliance.

Kedron's true mission is seizure of Demiurge. He leads a sixteen-man Sentinel strike team whose primary objective is the ship's computer core, where they attempt to install a Chantry daimon called Ship to take control of the vessel. After this effort fails, he uses his dead soldiers' comms to taunt Hadrian and threatens Cassandra to draw Hadrian away from the bridge, while planting explosive charges to destroy Demiurge's shield relay nodes. He remains invisible to Demiurge's systems through Chantry praxis even after the daimon's destruction. He engages Cassandra in the shield relay annex, wounding her with an electric discharge from his gauntlet, but is ultimately killed when Demiurge's uthras -- iron repair-machines -- swarm over him. Three of his Sentinels perish alongside him. Hadrian had foreshadowed, from the moment of their first meeting, that he would prove wise to have doubted Kedron.
