Filaur of the Gray Pillar:
If you leave the village and go to the minefield, you will see many Utuku Orcs. Bring me the Chrysolite Ore that you collect after defeating them. I will reward you based on the amount of the ore you bring back.
But more importantly, you should find out where the ore comes from. I ordered some investigators of the guild to find out, but I haven't gotten any useful information from them. I only know that there are many hidden chrysolite veins somewhere in the Spine Mine Field, and only a few Utuku Orcs know the locations.
Sending investigators was a mistake, because the Orcs now know that the veins are important. I hear they tore the Maps that indicate the location of the veins into many pieces and scattered them throughout the territory. If you find the pieces of the Maps, you must go to Priestess of the Earth Chichirin in the temple. She will help you to combine the Maps. I will give you a generous reward once you bring me the completed Maps.
