Wow! For the candies alone, you need 48 hours of kitchen time!
I'm curious how the rewards from this trade will compare to the rewards from the plume hive adventure. Both require a lot of the same materials - silver, jewels, sugar, cocoa, kitchen time. And I assume the tea cakes will need flour and even more sugar.
And I'm even more curious to discover what we will need all these faerie building supplies for. And whether there will be more expansions coming to provide room for new buidings. Very interesting!
