Dunno how that happened, but thanks!

Honestly not sure. I've heard that the EDAs have a world-building addiction but the Tractites are pretty well confined to the early chapters aside from Kitig. Jo and UNIT feel like the add-ons to me

@@thevacuumofcomments2946 So I can't comment on the _early_ EDAs, but the later ones had submission standards for new authors that *explicitly* asked you to write new things. "Although we have published a number of books featuring returning characters/races, we are very keen to go in wholly original directions in the future - as the TARDIS can go anywhere in space and time, there are an infinite number of beings and places the Doctor can visit. Gallifrey, the Daleks and Cybermen are definitely off -limits. And talking of which... We often receive enquiries asking 'Is it OK for me to...?' In general, if you feel you have to ask, it probably isn't something we want to see. New incarnations of the Master (or the Doctor!), adventures set before An Unearthly Child, the later lives of companions (or, indeed, their deaths), Blake's 7 crossovers, multiple Doctor stories, the Valeyard, more adventures for K9 and Company, new (or non TV/BBC Books) companions, Time Lord mythology or history, virtually any sequel to a televised adventure - these are just a few of the things we don't want to see, and in general they'll lead to an automatic rejection. That doesn't mean we will never a publish a book featuring any of the above - just that, if we do, it will almost certainly be specially commissioned from a previously -published author. For unsolicited proposals, we prefer to see wholly original submissions - you stand a much better chance of impressing us with your inventiveness and imagination that way!"

I'm sure it's just a coincidence
