OGL-25
OGL-25 is a planet in a contested zone between the Federal and Imperial space, so called Dar’s Pocket. This name was given to the area of space after the deceased Imperial Admiral Ivan Dar who allowed the Federal forces to reach all the way to Limmea under his negligent watch.

If it was positioned in a safer quadrant, OGL-25 would become famous among winter tourists for its gorgeous vistas.
By being on one of the narrow ends of the Dar’s Pocket, the OGL system is sometimes used by Imperial ships as a shortcut between Amaltea and Crina, that is the gateway to Limmea. Still, jumping across the Dar’s Pocket means prominent risks, as the area is rarely patrolled by the Imperial forces, while the bulk of the fleet is bound in battles with Federal raiding parties, or in protecting the inhabited worlds near the borders of the Imperial Space.
All planets of OGL system have been marginally surveyed by the University of Capitol, but none of them has been explored enough to be prominently mentioned in the charts or atlases. This is the reason why both Elza and Commander Pyr could not predict anything that was coming for them when they crash landed on the surface of OGL-25.
