Hi FoTV, I spotted this blog while reviewing some terminology on the site and I realized that this is one of my favourite decorations. Thanks for blogging about it!

I felt like you when I first realized it had been unused in the challenges but then I looked it up on the Wikipedia and discovered that the back story was both tiny and useful if one hinted at contexts by placing it near other objects. For example, beside a fusion chamber it can hint that one has discovered a secret of the fusion gods. There are also a fairy tale  and novel by that name not connected to Grimm's. So the connection to unlocked secrets which can be employed makes this more valuable to me than most other decorations which are obvious in nature. In this case I am glad that Tinyco did not spell out the connections, which might have ruled out our own ability to create village mysteries.
