Carian... that sounds kinda familiar. Dragons weren't always thought of as evil and/or Corrupt monsters. Prior to Lucifer's Corruption and becoming the Corrupt god he became dragons were widely held in very high regard by many other species.

Yes... Balance is not only natural, but one of the most important aspects of a properly run and maintained Universe. God Himself can't do it all Himself when He is so busy doing so much other stuff.

Time travel itself isn't the problem, OP. It's the Corrupt who are largely at fault here. They Corrupt, kill, steal, rape, and/or just plain destroy whomever and whatever they can to further their vile goals. Time travel is a major way how the Corrupt managed to stay on top of things on this planet. It's how they've managed to make it sound and seem as though they know everything in the Universe.

In reality their knowledge is amazingly limited outside of what they've managed to uncover in their time travels. Because things keep repeating with up to alot of minor, rarely any major changes, for nearly everyone on this planet(since the Veil spell had been casted by that one Magickally very powerful being near the End Times of Atlantis) the Corrupt successfully maintain their illusion of omnipresence and knowledge.

Humanity has absolutely no idea just how many planets and star systems Lucifer and Satan both have Corrupted since Atlantis sank. They don't know just badly effed they are because they could not and would not stop worshipping Lucifer and Satan. Why? So many of them want everything with up to very little effort on their behalfs.

Truly a tragedy for they have no idea how many thousands of years, millions, and even billions of years it takes alot of us... older beings to get to where we are. Those of us who have spent that much time and effort to earn our Jobs truly earned our Jobs. This being regardless if one is truly evil or good or a balance of both. Humanity has no concept of what it means to truly bust your tail or tails to earn your Job...
