After ten thousand years of dreaming, locked in stasis at the heart of his shattered home world, Lion El'Jonson wakes to the nightmare of Imperium Nihilus.
In this midnight age, the dying embers of humanity are threatened on all sides by the hungry darkness. Alone, even the Lion has no hope of prevailing against such evil – but there are those who would aid him in his quest. Hunted to the edge of endurance, many among his Fallen knights have long-awaited the day their liege would return to redeem them. The Lord of Shadowed Paths must gather these lost loyalists to his side once more, and stride forth to vanquish a traitorous son and the twisted Chaos warband that calls him master.
Faced with these strange times, the Lion can be certain of nothing and no-one, except for himself. But in a galaxy without the Emperor, without the Imperium, without his Legion, and without Caliban… who is he?
