Oddly enough, even the nomadic D'shar nobility, when exiled from whatever rights to their birthright, display a penchant for heavy armor and mounts like their noble neighbours around Pendor, unlike the Noble Cavalry found in the D'shar lords' warbands. What is even more surprising is the origins of some of their panoply, ranging from suspiciously Far-Eastern blades to Mettenheimic armor. These gear make these nobles quite a mixed bag, since they could either be armed along their traditional origins or look like total foreigners to Pendor.
Note: Keep in mind that this unit is originally the Foreign Rogue Knight, a unit with with the same non-D'Shar gear as above plus some more shields back in PoP 3.6. Removal of the Barclay and Mettenheim gear would suit the actual theme of the current unit more.
