Warhammer 40,000 Ark Crusade

In the violent maelstrom of the Horus Heresy, many of humanity's leading men who had fought for the Emperor and Warmaster Horus were thrown into the raging tides of the Warp by chance. When they opened their eyes again, they found themselves on a strange planet, filled with demi-humans and mysterious technological relics that had not been civilized by the empire - the most suspicious of which was a special black crystal mineral that was suspected of intensifying psychic reactions - the "Source Stone". In order to survive, they were weak and with no communication, they made their own choices on this planet called "Terra" by the local indigenous people. But they never forgot - this endless war between humans and Chaos is far from over.
