I noticed that you added a shop keep on the other side for grips i was wondering that once the castle was available to enter if you could make a miner shop or something basicly a shop where he sells the respectable ores the reason for this is that you must walk a pretty long distance to even purches this and you also still need to process the ore it self even after purches this would give you the choice of either buying the ingots for full price at the delivery service or walk up to the castle and buy ore for maybe a little discount but you still have to process it...
