After helping the Beast Archipelago deal with miasmic corruption and various other problems for a while, Rio and the rest of the group decided to head home earlier than originally planned.
Ashtel had already urged them to get going several times by now, as he wanted them to go back and help deal with the trouble that had happened back home instead of wasting time in a foreign land.
Rio and the others felt obliged to help, as they were already here and no one knew when they would ever be able to return again in the future.
As people with immense talent, the stronger they grew, the more responsibilities they would have to shoulder in the future, and sooner or later they would be too busy to go on vacations like now.
Even if they had to travel the world for healing the damage done by the demon armies in this incident, it would still take months before the turn of the beast archipelago would come and they would be able to come here again.
