And time rolls on.
Layla and Rana take a brief lesson together at the Great Library to try and train their newfound sorcerer abilities, but it proves less than helpful. Their wild talents don't fit into the regimented program of study, and in any case they only have a day in the city to train and many preparations to make for leaving. The one-hour lesson is enough for both of them to successfully cast Prestidigitation from the instructor's model, but that's all they have to show for it.
It's going to be a long journey - almost a month long, though there will be a few small towns along the way. They'll be traveling mostly in the Sphinx Basin, after all. The midpoint waystop is the small town of Kalit, which keeps the oral history of many travelers back and forth between the grander cities. The larger town of Djefet used to be the main waystop, but its people are now afflicted by a wasting curse: no wise traveler rests there anymore.
Layla and Rana prepare as best they can. They buy a cargo of papyrus to bring upriver to Sothis, and lay in feed for the camels and for the travelers themselves. Lost gear is replaced: worn gear is mended. Given that Baqir is essentially working for free, they should be able to make a tidy profit on this leg of the journey as well.
