From Warhammer 40k - Lexicanum
Arkhad was a Warden of the Blood Angels during the Great Crusade and Horus Heresy. The seneschal and commander of the Legion's garrison on Baal, Arkhad and his small force oversaw the planet's transformation into a major hub of loyalist activity and refuge following the Drop Site Massacre. Arkhad proved highly distrustful, considering the Salamanders Cruiser Ebon Drake to have been traitors for their suspicious behavior in trying to requisition supplies and intelligence.
