Hang Layden was a landmass situated within the expansive Southern Ocean found on the world of Kalimahr.
The island became embroiled in a land ownership conflict among three development companies sometime in the period spanning from 25,802 BBY to 25,793 BBY. The Je'daii typically would have regarded the situation as insignificant, but the location was believed to potentially contain archaeologically important remains; specifically, a possible Gree construction located one kilometer underground. Consequently, Lanoree Brock, a Je'daii Ranger, was dispatched to mediate between the involved parties, and also to secretly safeguard the ancient site. She accomplished this by utilizing Force illusions that depicted rockfalls and deep chasms obstructing access to the cave system leading to the ancient ruins; these illusions were designed to last for at least 100 years. Ultimately, she facilitated a peaceful agreement among the three groups, resulting in a divided control of the island.
