Variks is somber when you approach. Eramis's single-minded quest for revenge made her unfit to lead the Eliksni, but Variks mourns her all the same.
But there is little time to mourn. Variks knows new Eliksni challengers will rise on Europa. He agrees to help you and the Vanguard take down what remains of House Salvation.
Complete the "Sabotaging Salvation" mission.
