Forge of Mars, Warhammer 40,000

Legend tells of a foolhardy expedition, led by the radical Magos Telok, that ventured out into the unknown space beyond the Halo Worlds in search of the 'Breath of the Gods' - an arcane device with the power to unmake and reshape the very stars themselves. Thousands of years later, the ambitious Lexell Kotov musters his Adeptus Mechanicus Explorator fleet and sets out to follow in mad old Telok's footsteps. 

Pursued by vengeful eldar, Magos Kotov’s Explorator armada heads into a newly revealed area of space in pursuit of ancient secrets. As the Adeptus Mechanicus forces and Black Templars Space Marines tackle the twin threats of the wrathful aliens and insurrection aboard the fleet, a greater danger reveals itself.

In the great black void beyond the boundaries of the galaxy itself, Archmagos Kotov's voyage has come to an end. He has found his quarry at last – the resting place of the long-lost Vettius Telok. But Telok yet lives, and as the brave explorators of Kotov's fleet marvel at the wonders laid before them, darker plans unfold. As reality itself is threatened by impossible technologies from the dawn of time, it falls to a small group of heroes to thwart an insane plan that could see the very universe itself annihilated.
