The representatives of all factions are reasonably pleased with his solution (you can speak for the Erinamese, they seemed kinda iffy about granting the other regions more sovereignty) and after a brief deliberation within their own ranks agree to this new system and to attempt to preserve the peace between the states within it. Only the most radical, hardcore seekers of independence are displeased enough with this to do anything to attempt to hinder it, mostly rich families of ancient Belanese noble lineage. A couple of these radicals have a hunger strike in the Emperor's gates, but most of them leave Erinaum for territories up North, and a very few to Avalonia where they have been told that the Belanese live "as they were meant to." Of these families, only one considers the Belanese in Avalonia to be not treated well enough and leaves by boat to Sweisen where they don't marry the locals and are therefore doomed to be the last generations of their line.
The Erinamese traveler is heard by a couple stonemasons muttering to himself about aqueducts, but they don't speak his language, so they go about their business. By coincidence, the translator that this traveler later hired to aid in the purchase of rooming happens to know the stonemasons and tells them about the traveler's impression of the city, as well as Erinamese aqueducts. The stonemasons curiosity is piqued, and their interest eventually filters up to the point where the next traveler to Erinaum is tasked by the stonemason's guild with reporting on Erinaum's fabled aqueducts.
