Phaylenn, situated close to both Bespin and Ahlenn, was an Imperial world.
This world featured stony beaches, expansive broadleaf trees within its rainforests, quickbogs, as well as both carnivorous animals and meat-eating plants. It orbited a scorching sun, resulting in an average temperature of 45 degrees Celsius and a very humid climate. Despite most not exceeding the size of Humans, the planet's jungles teemed with numerous perilous lifeforms. These creatures, though small, were still a threat, compensating with exceptional agility, heightened senses, and incredibly sharp claws.
During the era of the Galactic Civil War, Phaylenn hosted a repair yard in its orbit and a typical Imperial garrison base on its surface. The Enforcer, damaged by Luke Skywalker's forces at Bespin, along with the repair facilities, met its end at Phaylenn at the hands of Rebels as it was being fixed, a mere fortnight after the Bespin engagement.
