After Jedi Master Thon defeated Sith spirits that threatened to take the sector, he contained their dark side energy beneath the lake. Over time, the power of the dark side warped the creatures of the lake, resulting in the creation of the vicious Hssiss.
During the Cold War between the Galactic Republic and the reconstituted Sith Empire, there were unusual evidences for life close to the lake discovered.
While waiting for a meeting between himself and Lord Skere Kaan, Darth Bane made camp along its shores, something those native to Ambria never did, as they gave the lake a wide berth.
Through meditation, a Jedi could draw minerals out of the lake and infuse them with the Force to create the Luxum crystal. This crystal was powerful against droids, releasing an ion pulse upon contact.
