These are the archives of the main uploads of Friendship is Witchcraft. Note: The original videos had been nuked early on but these later served as the main 2013 and capture a fair bit of history anyway. Unfortunately most of Sherclop's channel was nuked of comments before I got to it. The only upload of his that I have is Friendship Melody.

Surprising it and none of the FiW re uploads that I've seen to have been hit.

Now I've been a bit split into how I format these and if I could try to cobble something together to make them easier to browse though. Here is the bare bones JSON files.
