The Book of Harmony

When the oracle behaves strangely, Helena is its only hope.

With the Mercy's attacks on the Wardens neutralized, Helena prepares for her upcoming wedding to Malcolm Campbell. But when Helena steps into the oracle's space and finds herself somewhere unfamiliar, the mystery threatens to destroy the Wardens' tentative peace.

Having no explanation for the oracle's strange behavior, Helena reaches out to a new ally she hopes can answer her questions. Is the oracle trying to communicate with her? Is it under attack again?

Or is Helena traveling through time?
