The Jedi training ship Chu'unthor had many datatapes about the Jedi training. When it crashed in 340 BBY, Jedi Master Yoda lead a rescue team to the wreck. He left the datatapes and reader discs about the Jedi, and prophesied a Jedi to defeat the Nightsisters. In 8 ABY, Luke Skywalker fulfilled the prophecy and took the records. In 40 ABY, these were the majority in the collection of Jedi datatapes of the New Jedi Order.
