The Magic Treehouse/WMG
The Treehouse is a TARDIS
- Its chameleon circuit is also broken but its stuck as a treehouse in a tree.
- And ergo, Morgan le Fay is a Time Lord.
- Alternatively, the Treehouse is primitive TARDIS constructed with Arthurian Era materials and magic that Morgan and others would have known about, hence why it looks, inside and out, like a simple treehouse full of books, instead of a futuristic spaceship concealed within the geometric appearance of a simple treehouse.
