The Hour of Revelation

Shenaria's sacrifice was in vain, and the Temple lies destroyed...
The forces of good lie confused, scattered and broken...
A ghastly sacrifice engenders a diabolical summoning ...
Chaos and rebellion break out on all civilised worlds...
An innocent child is vindictively hunted down...
The Supreme Sanctifier succumbs without even realizing...
The insidious Enemy Within finally reveals itself...
...and a small, unarmed community at the foot of a mountain is all that stands between humanity and its final doom.
Shenaria is gone, and the End of Everything still beckons. Bereft of her leadership and wisdom, and separated from each other, Matthias and Modesty struggle to prevent the forthcoming apocalypse; but Modesty is betrayed and Matthias is on the run and wanted for murder.
How can they possibly triumph against the greatest evil of all?
