Lord Commander Eidolon is haunted. Aboard his ship, daemonic manifestations abound and threaten to tear it apart. Yet, even as he vanquishes it, he feels the pull to a world he once knew, and a reunion with a part of him thought lost. Lord Commander Primus Eidolon has claimed many titles along the annals of his infamy. He is the Exemplar and the Risen; the Soul-Severed; the Auric Hammer. Now, fallen far from his primarch's grace, he carves a path to Terra, where the culmination of Horus' grand Heresy awaits. But coaxed and goaded by the wiles of the warp - and an entity whose whispered truths stretch even his credulity - he finds himself stranded around the world of Tatricala, where the ghosts of his past haunt every fated step. And now he must make a choice which life he wants to lead... and how much of his soul he is willing to sacrifice for it. For if Eidolon cannot banish his daemons, then they will surely take him for their own.
