The Season of Death's Dominion is the fourth Proposed Serial of Spectral Shadows. It is preceded by Serial 4 - The Secret of the Willowdeer and succeeded by Serial 6 - Blinded by Science. It is currently not in progress, and therefore the only material available is the summary on the Synopsis Page.
The summary is as follows:
Jonathan and Raelian become estranged as Rael gains incredible powers while Jon is finding his faith increasingly in doubt.
Winter sets in, bringing starvation and invasions from predators that normally keep to the mountain. Meanwhile, human carelessness poisons the forest with toxic waste, and Raelian's new powers are the only hope of the forest's population.
Humans, seeking to cover up the toxic disaster, arrange for a massive mercy kill to divert attention from their clean up efforts. This quickly turns into a devastating free-for-all for The Astral Pirates who proceed to assault the forest with weapons meant for war rather than hunting.
