 Owner History
Armstrong was a part of the Erdvynn Province of the Rim Worlds Republic and is located near Milvano and Tatopani. Although Armstrong is detailed on maps within Handbook: Major Periphery States up until 2750 none of the maps from later eras present in the Handbooks series of sourcebooks extend far enough into the Periphery to confirm or deny the continued presence of this system during the Succession Wars era.
