The future of Mankind relies on the Guardian of Maarihk. Can Natharr, Ellis the Elder, and the Knights of Ril endure tragedy to stave off Mankind's dark future? The past and present collide, forcing Natharr and the rest of the Rilari to struggle with the consequences of their absence, past choices, and the power of the Usurper's vizier left unchecked for far too long. The strain proves too much for some, requiring hard decisions to prepare for a dark future racing toward the Guardian of Maarihk, Ellis the Elder, and the Knights of Ril. All that two generations of Guardians have planned from what their Sight revealed is on the brink of failure. They split their forces to race against time, gambling that thinner numbers will endure on diverging paths toward victory. Meanwhile, Nathan fights to deal with great loss and a change of course in his life in the Maarihk Empire as it plants new seeds yearning for a single goal: vengeance.
