Hi, I am stuck ad could like to ask for help (please!)

I have my tower and broken valley is not poisonous gas. I need a town to sell and buy things at – this is difficult without the ability to sell stuff off for cash and potions. I am sending my runners but they take a while and need better equipment, but I don’t have the cash. Is there a town somewhere?

I turned into a dragon and currently in a cave battling some real baddies and it’s a long slow process without a town to stock up at ! I have my runner getting me diamonds – but I have no where to sell them ? what do I do?
