The Vaungiur Mercenaries were formed by Cassandra Muir and Emmali Vaungier. They, along with Ameri Muir were part of a trio of Muir test pilots and mechanics who worked at Radion Labs and later Kuat Systems Engineering. When they were at KSE, Ameri met and fell in love with Jax Sage, which brought the number of bachelorettes down to two. When it was time for the three to leave and go on with their lives, Ameri opted to go with Jax on his brother's ship, the Sage's Destiny. The three parted as friends and Emmali decided that it was time that she returned to her homeworld, Silseris for a visit.
