Having escaped the grave of Nonezzeron, the Heroes of Bingle trek further into Shaxen Gao territory. But when they reach a fork in the road, a disturbing message from a family member could mean they're running out of time. As they quicken their pace on the trail of the Quake Warden, a massive clue seems to imply they're on the right track in this strange new territory.
