Issinium is a Imperial world that was brought into peaceful compliance by Horus Lupercal himself during the Great Crusade. For nine days Horus feasted with the High Concern, the rulers of Issinium, while listening to the oral history of their world being recited for the duration of the feast before the world agreed to join with the Imperium.
