Olanca was a male Moonlight Elf who had a relatively high status. Hundreds of years ago, the Moonlight Elves had left the Forest of Life in Sylve.
After they left, they had developed their own belief system. Specifically, the Moonlight Elves believed in the goddess of harvest and earth. They lived in the Silver Moon Forest in the northern part of Yala, which explained their belief in the Lord of Natural Order.
The main differences between the beliefs of the elves and those of human beings regarded resources, among other things. Specifically, the beliefs of the elves were more focused on inner resources, which were interpreted as the will of nature by the elf poets.
Basically, this meant that all of the elves must protect the forest and coexist with nature. Even the elf wizards had to believe in the Lord of Natural Order and love the forest.
