Using the ancient magic bestowed upon them as their guide, Sylvie and Jack traverse the icy ranges that surround the Diamond Alps. The core of the four Institutes, however, is not as tranquil as its silent gateway suggests. Behind the scenes, an internal struggle for power rages as the Zenith Council strives to elect their new leader. Gridlock among the Diamond Alps' top brass has brought the entirety of the north to a standstill, and the pair arrive just as tensions peak. But Sylvie and Jack quickly realize that the real danger does not lie within the Diamond Alps, rather in the snowy plains outside of it. The mountains that make up the north are home to a heinous secret. A forgotten god tied to the past slumbers beneath a once venerated altar deep in the heart of the mountains. As events spiral out of control, the ancient plot that devastated the First Zenith is finally dragged into the light. Bearing the burden of Thelarius Merve's legacy, Sylvie and Jack must face off against the bloody ambitions of a man they believed long dead in one last epic struggle.
