His three sons died within 14 years. Coincidence that it ends not long after De Molay said it would? I doubt it.

Who knows if Dagobert was assassinated or not? If he was, it would be natural for the courts to decide not to release the information to the general public, as it would show bad security and show that assassination of monarchs was possible. History would probably be rewritten, as to not show the lax security that was there.

If you read a book, Philip and Clement weren't assassinated either, but if you think about it, what are the chances of a leader of an order that was destroyed by the two of them cursing them to die within the year, and then that actually happening without Templar interference?
