Our heroes find themselves crossing between strange, deadly, beautiful worlds, pursued by a foe they cannot comprehend. Can they grow strong enough to defeat their cosmic enemy? Or will their journey take them down a road from which they can never return? Magnus leads an expedition. Taako is tempted. Merle leads his congregation.

We're nearly at our journey's end -- but before we can understand what lies ahead, we must first return to this story's true beginning. What brought our heroes together to the crisis they face today? What happened to the memories of their dear, forgotten friends? And just how long have they been running away? Taako learns a new language. Merle eats some beans. Magnus trains under an unlikely teacher.
