Early in the First Havenite-Manticoran War, the ship was escorting a freighter transporting missile technology to the Alizon System when they were ambushed by Havenite privateers. The freighter was able to get away, but Ellipsis was taken after her bridge was hit, killing the captain before he could give the self-destruct order. The battered vessel was then towed to a hidden spacedock. Although the manticoran crew destroyed most of the sensitive material aboard, the Havenites found some personal service manuals in lockers and a few hardcopies of routine diagnostics that were still intact.
