Spoilers for chapter 1368 of Turning.
Melborn's training is finally complete, with Alik having managed to create a control device that not only reduces the adverse reaction of using the ability in a specific area but also decreases the fatigue and exhaustion Melborn feels when using his abilities, thus bringing the journey to Nerlan closer.
I'm really looking forward to seeing the Nerlan arc, where we'll probably have another major conflict involving the Wolf Eye tribe and very likely the emergence of another rift and who knows, maybe some terrible monster. Considering that Yuder never said anything about a disaster happening in Nerlan (which, if I'm not mistaken, was one of the few places that didn't suffer from the rifts in 1TL until Yudrein's death), this could be an even greater challenge than the Southern Disaster, since Yuder will have no prior information to base his plans on and try to prevent the disaster, especially if they can't stop the Southern tribes.
