With the size of their troops, it took them nearly two weeks to leave the borders of Harune.
Alaric could have returned home early if he had chosen to ride Zephyr, but he decided to march with the troops because he was looking for an opportunity to use the Catastrophe-Grade Steed Card.
If he were to use it and summon a beast at the estate, he wouldn't be able to explain how he had captured or taken control of it.
He was only lucky that his family didn't have many questions about Zephyr, but he couldn't do the same thing again. Lucas and Maria might not be the interrogative type, but his birth mother, Jade Kristine, was different.
He had to make a reasonable story so that no one would find it unusual for another Catastrophe-grade beast to appear next to him.
At this moment, the troops were setting up camp. They had been marching with little rest over the last two weeks so Alaric suggested that they should set up camp and rest for the night.
