The walls are closing in around Kerak Um.Tiago. Now an outcast, this failed operative had once idolized his lost father and older half-sister, both masters of the craft to which Kerak had devoted his life. But no longer. Once the hunter…now the hunted.
Enter the Sphere known as the Dimensional Horizon: a realm of rugged terrain and unfathomable seas, illuminated by winged iridescence, lying above the cavernous architecture of the nebulous Subterra, beneath the deadly Mists of Aurea. Here, the renegade Muricai, on the brink of annihilation, has stood alone to oppose the ruling Triumvirate and its legacy of pillage, subjugation and death. Here, a family, torn apart by time, distance and divided allegiances, is driven somehow to heal, both within and between. A Sphere, ravaged by conflict and darkness, wills itself to do no less.
With half-brother and Muricai loyalist Drogan Te.Sinian, Kerak joins forces with the Horizon’s most reviled apostates, exiles cast upon a desolate shore. Forced from sanctuary by the machinations of a distant specter, now begins their tortuous journey to decipher the Circonic, an ancient vault of mnemonic erudition. Its most coveted yields…material, spiritual and psychic…reveal evidence of a looming cataclysm, one which must be directed at the Triumvirate to sever its malicious grip on the very heart and soul of the Dimensional Horizon.
