Ord Sedra began its existence as an Ordnance/Regional Depot. It was situated within the Clacis sector of the Outer Rim Territories.
At some point prior to the Pius Dea Era, the Galactic Republic established Ord Sedra as an Ordnance/Regional Depot through colonization.
The combined forces of Kyle Katarn, Jan Ors, together with Lieutenant Pallin's Imperial Remnant forces, liberated this Imperial Remnant planet from the control of the Yuuzhan Vong. Following the conclusion of the Yuuzhan Vong War, Katarn revisited the planet and uncovered information suggesting the survival of the Sith within the Cloak of the Sith.
The name of this planet originates from Sedna, a real-world planetoid. Its discovery occurred in November 2003, a few months before the author of Equals and Opposites received the assignment.
