Hidden Valley Mines
After the founding of the Pioneer’s Colony the mine yielded a steady supply of ore for years. It did not take long though before a band of Goblins launched a surprise attack. They even brought cave crabs with them as if to publicly announce that the ore was now theirs.
In light of the goblin’s attack and the crab’s furious digging, the mine’s stonewalls became loose. That was the moment the humans decided to abandon the mine in order to focus on the ore vein to the west of the settlement. This was a temporary measure until all goblins and cave crabs could be driven away.
