The Great Tree has taken root, but the desert is a harsh soil.

Valla, the dark shaman who went mad in her quest to kill Oskar’s Collective, has fallen, freeing his brother from the terrible hold she had on him.

Desiccation doesn’t care about battles won or lost, though; it’s fighting a war. Its corruption marches toward the Great Tree to unravel the last chance this world has, leaving Oskar and his friends no choice but to destroy the corruption at its root.

Danger beyond anything they’ve ever faced awaits them, and rumors swirl of a familiar traveler fleeing across the desert, whispering poison to any who will listen.

Even the arcane knowledge Oskar gains to stop the Desiccation threatens to unmake him, and all the elemental powers he’s mastered might not be enough.

After all, in an endless desert, a little rain isn’t going to cut it.

To save a world turning to dust, Oskar must become the storm.
