Preparations

The reason why Malo and the others came up with a recruitment method for the sect was because Freedom Island had also received quite a few airships with ex-human slaves in it. With the sect's help, everyone there was given some land where they could build their own houses. Obviously, it was also located in the south of the island. 

Another good thing was that Freedom Sect was already used to farming. One must not forget that its carrots had a great use during the time when the Underwater Palace was attacked. In fact, Red had been mostly taking care of the farm until now. He wanted to grow the best carrots ever...or so he said. Rean then told him to help with the other farms.

With that, it wasn't hard to take the necessary land for farming to grow food for the people that arrived. At the very least, the humans dropped in Freedom Island were in a better condition than most humans in the Wringan Mainland. After all, they received the help of the cultivators around.
