This is a brilliant idea! The only thing that's missing is the ability to go back as you normally would while browsing a wiki on a browser, so if you fall down a rabbit hole you can't 'go back' all the way to the top of the rabbit hole and fall down a different source. I know that's a limitation with the engine, though, so otherwise this is brilliantly put together!
I figured it was a limitation of Twine! It is all brilliantly done! I could feel the appreciation for the genre, and boy- do I wish Excalibur had been a real show. I am still having a great time going through all of the entries in detail. As a sci-fi fan, space opera fan, and an Arthurian nerd, this hit the right spot perfectly.
