Following the beginning of Commander Eldex's uprising against Overseer Gaul, Sahen was contacted by a group of Vaadwaur dissidents in the Gerren system who sought political asylum from the Alpha Quadrant Alliance. She negotiated a deal wherein the Vaadwaur in question would trade some Vaadwaur technology for their safety, but forwarded it to an AQA flag officer for approval.
