Yokan led Athan to a Firmament Chasm before both of them traveled for some time.
After an hour, Yokan took out a medallion and did something with it, which produced a portal. Both of them entered inside that portal and arrived at a hidden island.
There were a few people of the same clan as Yokan on this island.
Seeign Yokan with a stranger they didn't recognize, they asked who he was and whatnot.
After ten minutes of talking and other things, they entered another portal inside the palace on this island, which led to the Main Devil Realm.
"I changed the portal's coordination to match with a small manor I have in one of the biggest cities in Main Devil Realm, the Lugian City, " Yokan said as both of them arrived in a room, which was Yokan's private manor.
Athan nodded and said, "First, I want you to lead me surging spots filled with powerful energies; there should be such spots here, right?"
