No world can stand.... Moments after Sen stepped through the revenant arch, an inky darkness flooded out across his world. Over the wreckage of a city broken by revolution it surged, engulfing the grand Grammaton tower, smothering the King's Aigle palace and drowning every last caste in the dark. Sen alone escaped; a young man prophesied to raise the Saint and save his world for good. But he failed. Now his world is gone, and his friends are just memories swallowed by the endless dark. Now those memories haunt him, trapped in a strange white cell with no possible means of escape. Now a lost figure is watching, a clocksman who claims to be 300 years old, seeking to fulfil an ancient vow.... And now, the Rot is resurgent, its great black mouth spreading wide across both the future and the past, unleashing a terrible hunger that no world can withstand.
