Nos Astra Sporting Goods is located on the Presidium Commons of the Citadel. The terminal is found at the counter of the left shop on the lower level of the Meridian Place Market. Note: Because the Citadel is inaccessible after Priority: Cerberus Headquarters, the Serrice Council Greaves, if missed during the mission, can only be purchased through the Alliance Requisitions procurement terminal in the Normandy's shuttle bay.
