Every few decades or so a series of books, journals, pieces of paper and sometimes even pictures gain the ability to send and receive messages from the planet Earth to the land of Equestria. No one knows why this is, but with time and patience we have managed to start collecting records of all letters sent or received starting from the date of March 18th, 2012 between the two realms.
The results are open to the public.
(Will add characters once mentioned. Accepting submissions for new 'letters' as we speak. The Dark warning is more for 'Mature' then anything. Things connected to the human world generally are.)
(The Picture isn't mine. I'm not really sure who it belongs too, to be honest.)
