"As everyone has already been to the designated place. I will tell you about your work. Once every five years, the magma in that place gets more agitated and a large amount of magma is expelled. At the same time, some rare minerals are expelled together. Your task is quite simple.

Eighty percent of what you found will belong to the guild and the other twenty percent will belong to you." The old woman explained.
