The Knurled Highlands, a region located on Iope, which itself was a moon orbiting the planet Rinn, were characterized by a significant abundance of berry shrubs. At the point of the Galactic War conflict, which was fought between the Galactic Republic and the reconstituted Sith Empire, the presence of these shrubs constituted the sole remaining clue suggesting that settlements had once thrived in the Highlands.
Approximately in 3637 BBY, someone involved with either side of the conflict dispatched an associate to explore the potential for discovering further indications of past habitation within the Knurled Highlands.
The Crew Skill mission known as "Iopean Harvest" referenced the Knurled Highlands; this mission was made available as part of the Shadow of Revan Digital Expansion (2014), which augmented the video game Star Wars: The Old Republic (2011) developed by BioWare.
