Milvian
From Warhammer 40k - Lexicanum
Milvian was the second largest city of the planet Euesa.[1]
During the Horus Heresy, Euesa's government declared their support for Horus. This later led to Euesa being invaded by Imperial Loyalist forces. Milvian was the primary target for the Loyalist force's Imperial Army detachment, which was led by vice-Caesari Marcus Valerius of the Therion Cohort, while the Space Marines of the Raven Guard Legion led a focused decapitation strike on the Traitor government's leaders.[1]
