The MSV Strontium Mule is an Athabasca Class freighter under the command of Jarett Barnes. In 2185, the engineer repairs the ship's FTL drive with substandard parts. Shortly afterwards, the ship responds to a distress call from a planet in the Decoris system. Upon arriving, soldiers of the Blue Suns commandeer the freighter. The freighter then travels to the Arinlarkan system. In that system, the Cerberus starship Normandy SR-2 intercepts the freighter and a team led by Commander Shepard neutralizes the Blue Suns soldiers and recovers a valuable package. Of the nine crew members who serve aboard the Strontium Mule, none survived.
