The Outer Rim Alliance came into being as a group of displaced individuals in the Outer Rim. This organization was established because the New Republic lacked the capacity to protect the Outer Rim from the Yuuzhan Vong menace.
The genesis of the Outer Rim Alliance can be traced back to the Battle of Shramar, an event that underscored the New Republic's deficiency in safeguarding remote Outer Rim planets against the Yuuzhan Vong. It was established by those who fled the battle, congregating in Wild Space. Those seeking refuge from Artorias, led by Queen Nina Galfridian and Princess Kaye Galfridian, and Arbeloa. allied themselves with New Republic troops from Dibrook and the adjacent territories, commanded by Admiral Bylsma. Furthermore, certain Imperial Remnant units originating from Shramar, under the leadership of Captain Bristow, alongside a diverse assortment of pirate, smuggler, mercenary, and other privately owned ships, joined the cause.
