Eisen followed Gran out of the arena and was looking for a good place to set up his portable shop for now, and as it turned out, Gran's personal house was right around the corner from the arena that he was usually fighting at.
And even more luckily, he had quite a large open area. From the outside, it really just looked like something like a weird hill to Eisen, but the old man, Gran, Gran's mount as well as Ambriel swiftly entered through a simple cave.
It was twisting around a bit, and if Eisen didn't know any better, he would think that this was an actual natural cave-system. But at some point, they left the cave again, and found themselves in the area that was inside of the hill. It covered a rather large area, even larger than it let out from outside, and the top was open so that Gran was able to see the sky from here.
