While Walker and his team stayed resting for a while, others had already started to move.
There had already been plans for some healers and farmers to come. However, to reclaim the lands that won't be affected by a natural volcanic eruption, they needed one of the more unique classes that appeared lately.
The wilderness farmer was a class that appeared as farmers were trying to learn about the changes in pants due to changes in manas. While there was the worry of chaotic mana, they had also developed new farming practices.
In that respect, it had been a lot of time and work. To the point where many people working on these projects brought their families with them. Not that they weren't a farming family anyways.
Since the younger children without defined classes and skills who were still panting managed to obtain the class wilderness farmer. A few younger farmers even managed to change classes using quests that appeared.
