40K of gold, 400K iron, and 40K food appears to be the cost of unlocking the fountain.
Since the amount of iron required is ten times the amount of the other two resources, I'm hoping this is a typo and not the actual cost.
Thank you
this is not suppose to be easy to achieve or upgraded quickly. It will require a lot of your regular castle to be maxed to be able to continue growing in stoneheart. It sounds like a lot but once the rest of your castle is completely developed, it will give you something to spend all of your piled resources on. I will double check if it is a typo though, it does seem like one to me.
