Time travel sounds like an amazing idea because if we can travel to the future or the past, we can fix anything that has not worked out properly in the history of our planet. We could stop what was, warn people about natural disasters and much more. There are very few people who can comprehend how devastating this would actually be and that is the main reason why the order decided to bring down the operation that was already showing signs of being incredibly powerful.
There was a single successful time travel that was done to the past and
it changed things so severely that the order had to do a series of time
traveling missions to wipe everything out and get to the source of the
time traveling invention. There is no doubt that time traveling is too
dangerous to be allowed in any way at all. This is why we have to be
extra careful not to let it be used ever again.
