History
The Watchers visited this planet to provide scientific advances to its inhabitants, the less advanced Prosilicans, who then used their new knowledge to build weapons and wage war on other civilizations, which eventually led to a final battle that wiped out 9/10s of the universe, leading the Watchers to seal off Prosilicus and the other devastated parts of the universe with a barrier. The shut-off area became known as the The Barrens.[2][3]
