The Fog is expanding. No one has been able to find its source, which means no one has been able to stop it, which means the destruction of the world is no longer a question of if — only when. In one of the last settlements outside the mist, a place called Asala, two friends are finishing their training to become knights: the cynical Aeyr Wilder and the warmhearted Mia Alacruz. They are on the same side. Then something catastrophic tears their world apart, and they find themselves on different paths — paths they each believe are right, and paths that may not allow them to remain in each other's lives. The apocalypse is the backdrop. The friendship is the story.
