Anyone know if there is a good list that says what the merchant resources do? For example, timber. I thought I read somewhere that you could get a building by having a merchant on it or camels that says it allows you to recruit camel units which I've yet to see recruitable in Ireland which is where the particular node is. Another would be the dog resource or wool. I'm sure they're are others which is why I'm curious what they do and if there is a list.
