4th Dimensional time dilation reversal warp drives

The Galaxy is very very large and slower than light engines I.E. Classic 3rd dimensional drives are very slow. so Galactic colonization would need a very powerful upgrade in the form of a 4th dimensional warp drive. A 4th dimensional warp drive, taps into demonic energy to enter the fourth dimension and allows faster than light travel, but there would in lie a problem. Einstein found that the faster you move, the quicker in time you would move, this posed a problem to a lot until a Dreuvalk Scientist, known as "Aledegarn" found out the recipe to reverse time dilation via, slowly moving back through time, matching the speed, the destination, and the intensity of the dilation to find a formula to reverse time dilation. So you can move through out the galaxy in a reasonable amount of time. It wouldn't be until Swebia's time that it was found out that Demonic energy can move throughout higher dimensions, meaning that you could go to other timelines, unlike Swebia's own ship, which is thought to have an 11th dimensional drive, therefore letting him travel the Omni-Verse.
