Helios' eyes were wide as he was introduced to a whole new world with such tall walls and buildings. Alterra also had a few tall buildings, but he had never seen them done to this degree.
Back in Terran, he traveled a lot, and he could compare the size to the cities there and he could say that Bleuelle—and likely most cities in this world—were definitely on the larger side.
This was understandable. This world probably had billions and billions of people, too, but it was much more dense due to the dangers of places outside the territories.
