In late 2199, Mirangal was commanded by Colonel Neredia Rikke. In the course of its operations, Mirangal led a task force to rendezvous with the carrier Lanbea, which had been heavily damaged in battle and was now under the acting command of Major Fommt Berger. Soon after repairs were made, Mirangal and the rest of the task force became lost within an unknown region of space and encountered the mysterious planet Shambleau.
