Information

Adrantis Five was a human, hyper-technical planet which had been separated from the Imperium for over five thousand years. It was conquered by Lord Commander Solar Macharius during the Macharian Crusade in the Segmentum Pacificus.

The planet's population were hyper advanced, and when Macharius arrived he said that they had 'turned to the dark certainties of science, and created many new and wondrous machines'. Even so, Macharius still had to conquer it. He was held at bay for two years until the planet finally succumbed to a redirected comet. 'Of its secrets, nothing now remains' were the last words of Macharius on the subject.
