Geromidas
Geromidas is a Grey Knights Chaplain and a member[1a] of Epistolary Graucis Telomane's Brotherhood of Thirteen.[1b]
History
He was among those who greatly aided Telomane's efforts to prepare for the Daemon Primarch Angron's banishment in M42. This was done by collecting trinkets and curios from the deceased Grey Knights, who took part in the First War of Armageddon.[1a]
During their final battle against Angron and the World Eaters aboard the Conqueror, Geromidas was slain by a horde of Khornate Daemons.[1c]
