as per your request commander i have called up what information the munitorium provided us on “Stag Riders of Marr”
the world of Marr is a world of forested, rough mountains and lake lands. it is ruled over by a chivilry culture similar (but far less complex then) the Knight houses, seemingly based on the old knightly ideals from ancent holy terra. they world has been part of the imperium since the great crusade and provides troops well versed in mounted combat. their troops are excelent scouts and vanguards coming into their in: forests, rough terrain and open ground, when a force of vile dark eldar raiders set their sights on the world they came to learn the world has claws, according to the reports the horsemen’s knowledge of wilderness allowed them to run successful strike and fade operations against the dark eldar, blindsiding the xenos whenever they tried to attack settlements then they lured the eldar into attacking their main stronghold. but when the xenos attack came the eldar made the mistake of attacking just as the winter was to break. In the space of minutes the eldar troops were drowned in snow which rained down like a shower of razor barbed spines which on contact surfaces set hard as concrete, not only were the xenos foot troops stuck in their tracks but their jet bikes and vehicles suffered adverse reactions as the snow hit their engine intakes and expanded, gluing turbines and the like together.
once the flash storm cleared, out of the stronghold rode the stag riders and ran down all most of the xenos, dogging the few who escaped all the way back to their ship which an imperial navy ship then destroyed as it tried to leave the system
