The Coronus Grav-carrier grants the Legio Custodes a degree of speed and agility unmatched by the grinding armour of the Imperium’s other hosts, allowing them to deploy, redeploy, and evade without risk of being pinned down by enemy troops or hazardous terrain. They are both the primary transport for the Sodalities of the Legio and the template upon which several other grav-craft are based.
