Wrea existed as a planet situated within the Outer Rim Territories of the galaxy.
The planet of Wrea resided within the region known as the Outer Rim Territories. Its location made it challenging to access, largely because of its proximity to the Smuggler's Run asteroid belt. Predominantly, Wrea's surface was made up of vast oceans. Small, rocky land formations dotted the landscape, featuring vegetation such as grass and scrub brush. It served as the homeworld for the aquatic Wrean species.
The climate of Wrea was typically cold, and the air carried a salty scent from its extensive oceans. From an outer space perspective, it mainly presented a blue appearance.
In the period of the Clone Wars, a Separatist force was stationed there, maintaining at least one facility, which included a comm tower. After the war concluded, numerous deactivated battle droid units remained scattered across Wrea's surface. Later, during the Imperial Era, the freedom fighter Saw Gerrera chose this planet as the location for a base for his Partisans rebel organization. After Galen Erso was captured, Gerrera saved Galen's daughter, Jyn, and relocated her to his Wrea base.
