Thousands of years ago, a huge meteorite smashed into Nemaka, leaving the crater and blowing away the atmosphere. All life on the world was extinguished. The planet became the location of a xel'naga temple.
The temple had become inactive after the initial terran visit, which prompted Valerian Mengsk, son of Arcturus Mengsk and an archaeologist, to send archaeological expeditions to study the temple several years after the Brood War. Unfortunately, the first three missions failed to discover anything useful.
Jake Ramsey, leader of the last mission, theorized the temple had a similar function to the one found on Bhekar Ro. Ramsey discovered a secret within the temple. However, he became a fugitive rather than divulge the secrets to Valerian Mengsk, as he believed Mengsk had turned on him.
