Alibi_factory on LiveJournal has made a series of maps, under the guise of a TARDIS instructional pamphlet, of the TARDIS that belongs to that particular Time Lord who goes by the mysterious moniker of the Doctor. We’re fully willing to take these as canon, expecially since if there’s any inaccuracies between these maps and the actual show, well, that’s the TARDIS all over, isn’t it? Besides, this TARDIS has a cafe that serves crystallized aallaf tree sap. That stuff is so hard to find.
I’ve put my eight favorite pages of Alibi_factory’s pamphlet here for your perusal, but there are more than fifteen over at their original post, with links to high-res pdfs suitable for prints. You should check those out too!
