Lieutenant Marie Durand is the acting commander of the 14th Regiment, 3rd Brigade, Alliance 10th Frontier Division on Nepmos. She sends a mayday asking for assistance when she and her men are attacked by hostile lifeforms. After landing on Nepmos, Commander Shepard meets Durand at the listening post. She is tough-talking but exhausted after resisting sustained attacks by rachni. To Durand, it does not matter that these 'animals' are actually a sentient species, as they are still extremely dangerous. She co-ordinates her remaining forces and holds the line with the help of Shepard's squad.
