What the Codex treats as established
The Ikarion Guard is Human-founded and Human-dedicated, while members from many lineages serve beneath the same sworn order.
The Guard protects routes, convoys, refugees, fortresses, relays, archives, and evacuation corridors. Engineering, medicine, logistics, and rescue are core duties beside combat.
Its institutions include the High Marshal’s Council, the Corps of Fortress Engineers, and the Order of Relay Wardens.
