Before Quinn had entered the camp site with all of the Durum and others, his clone had reached the area first causing chaos. However, Quinn had released not just one clone but two clones.
One of them was busy attacking the base, the clone seemed to be strong enough to deal with the demons so he felt that there was no need for two, and even if there was, the second clone was dealing with a much more important task.
The clone had gone past the camp and in doing so it was exploring the rest of the planet they were on. From the information Quinn had received he knew of two things, for one that there is one that is called the champion somewhere on the planet as well as the demon king.
Not travelling with others and having extra help, this clone was able to put its full attention into exploring the planet ignoring the demons until it saw something interesting.
