Tetrarch

Santhenar is on its knees. War with the forces from beyond the Void shows no sign of ending, and there is worse to come. The Aachim have invaded with a fleet of formidable battle constructs and the price for their withdrawal is half the globe.

The future of the world now rests in the hands of just three flawed individuals: Tiaan, whose geomancy holds the key to a power that can yet destroy all foes; Nish, who has sworn to bring the renegade geomancer to justice; and Irisis, whose great talents are hidden even from herself.
