The griffins were very fast. They had left after noon, and the griffins had already started their descent as the sun started to set. They stopped on a hill, and right away, someone came over to help untie them, as well as help those who were so dizzy they could not even find their bearings down. After that, the griffins were brought into the specialized cages and fed.
These fixed routes were a mode of transport introduced by the colonists. Originally, griffin-riding required a lot of skill, but considering the fact that most of them would not be so skilled at riding, they decided only a landing and takeoff point was needed. They would then let the griffins get familiar with the routes, and did not longer need to be steered after that. The griffins would be able to get to the destinations themselves.
