The Lion. Son of the Forest: Mike Brooks

The Lion. Son of the Emperor, brother of demigods and primarch of the Dark Angels.
Awakened. Returned. And yet lost.
After ten thousand years, Lion El`Jonson finds himself trapped in the nightmare of Imperium Nihilus, where the dying embers of humanity are threatened on all sides by the darkness. Alone, he has no hope of prevailing against this evil. However, there are those who would aid him in this quest. Hunted to the edge of endurance, his fallen knights have long awaited the day their liege would return to redeem them. Now he must gather them to his side once more, and ride out to vanquish a traitorous son and his twisted Chaos warband.
And yet in these strange times the Lion can be certain of nothing and no one except for himself. But without the Emperor, without the Imperium, without his Legion and without Caliban… who is he?
