Since he could not fly, nor he would ever dare to, it took Ryker few more days before arriving. It is slower than flying which would take about a day flight, but in the end, the need for safety, especially after the near death experience of being chased by Genesis Lake bandit make it a good decision.
Once they are close enough, to the point they could see the walls of the city, Ryker quickly get the others out of the Hidden Ancient Mansion, to their delight. It is too bad they are not strong enough to bring out his siblings, but their safety is more important, especially when they could not even hope to fight their enemies.
