Endion

"There's got to be somewhere out there the aliens haven't touched... some undiscovered paradise waiting just for us."

- Ariel Hanson

Endion is a forest moon orbiting the planet Bellum IV. It was once a retreat for Khalai scientists to do research, and held the ancient purifier vessel Cybros in stasis. During the End War, it was overrun by the zerg, and then purified.

Research Retreat
Endion was a research retreat for protoss scholars for thousands of years, where they could seclude themselves from political affairs. Civilization-changing inventions were created there, such as the psionic matrix.

After the Purifier rebellion, Endion was chosen as the planet where Cybros would be kept in stasis, and secured by a Megalith. Khalai scientists would continue improving the stasis grid, and the station would serve as a both a symbol of scientific achievement and a reminder of the dangers of it.

End War
During the End War, the Amon Brood descended on Endion and overran its population, infesting the planet. However they could not break through the stasis grid that kept Cybros in orbit. Hierarch Artanis arrived with the intention of recruiting the ancient purifiers, and fought through zerg on the surface to guide the Megalith to the stasis locks that held the station. The operation was successful, and Cybros was freed.

After a battle to purge the zerg and hybrid from Cybros, Executor Clolrion fired a purification beam from his station, purifying all life on Endion. All zerg on the surface were annihilated.
