Although they still have work to do on the Fourth Section of the Coal Mine, it is never a bad idea to discover more portions of this Coal Mine before time. They have big orders to fill every month, now that it is winter the orders can and will increase.
Actually, the Coal Order has been turned in to continues. As long as this Coal mine is functioning, Bale Town will have orders to fill in for the Zamerians. Now since that Continent has richer folk who prefer coal as a primary heating source, the monthly order has bounced to 10 tons a month!
Obviously that's a lot, the town has a lot of work to put in, exploring a new section sounds an even better idea now right? They have to be prepared, they have a good name in front of the Zamerians yes but they can not risk losing such money because they are late with their progress.
