Isaac's traveling group of warrior Adepts first sees the pair in the town of Kalay staying at the inn with many other people from across Angara, and they are all part of a tour group that's on its way to Kalay Port at the eastern edge of the Karagol Sea, where they will take a ferry across the sea to the town of Tolbi to make it to Colosso hopefully in time. Ouranos, however, wasn't aware until right when he leaves with the tour group that traveling to Colosso would involve a voyage; Ouranos has a slight phobia of riding in boats because he can't stand water, and would have opted not to come otherwise, but the portion of Silk Road that bends above the Karagol Sea has been blocked off by a landslide, so travel by ferry is the only possibe means of reaching Tolbi.
