Star Clans Heraldry originated with the unit pennants carried by the brigade of genengineered soldiers stranded on Arden. The brigade was heading to do battle on a low-tech world, and carried unit pennants based on the style of their target world.
Over time, as the Uruki forgot their origins, the military symbols were simplified into stylized icons or replaced by icons with local meaning representing the kingdoms and clans. Uruki pennants have typically been dark ink on pale leather, without additional color. Since the founding of the Ardeni Kingdoms, the use of color has slowly been added, though not yet above the Family level on Arden itself.
