Fresh from reading the great HORUS RISING by DAN ABNETT, and unable to find much artwork relating to the Interex civilisation I realised I would just have to flesh out some of these concepts myself.The 'Sagitarr' are a human warrior class, that use both bow and spear as main weaponry and sometimes ride upon a robotic headless horse, this gives the sagitarr the appearence of a centaur (Sagittarius)basic ideas behind this concept are .The Interex were not as warmongering as the imperial crusaders, I have read someplace that if the space marine crusaders were the "Romans" than the Interex were the "Greeks".The interex civilisation used mathematics and music to communicate with xeno species that they encountered so they are about beauty as well as functionThe armour was to be very light on the top half, to allow for free movement with archery and spear throwing, the thigh and greave sections of the legs are more heavily armoured as they are more exposed here. This is also where the riders armour and the horse construct meshThe helmet style is influenced by spartan helmets with a touch of rocketeer thrown in.The Horse construct, apart from carrying the rider into battle also serves as a mobile armoury for the Sagitarr as it can carry large amounts of throwables.
