This is going to be slightly confusing for some, and slightly long through theories. But don't knock it till you read it. And don't just NO it right away. As Orph has Time Devices as well. And it's NOT Time Travel. It's Timeline Manipulating. Alright so...
Temporal Parallelization Field: Going with the theory of time (see below.) This device will radiate a field of timeline parallelization and turn the time back in only the field and the objects within the field to the point given. This field is not very large and can only go about as big as the around a planet/star or two. Now...how this actually works?
-------------------------------------
Theory of Time and Infinite Timelines:
Taking the most popular theory of time. There are infinite timelines and possibilities. Every event or action in the world, has infinite results and thus routes.
Example 1:
You come to a fork in the road. You can either take; Result A:Right, Result B:Left, Result C:Go Back, Result D:Just Stand There, Result E and many many other possible actions. Let's say we went with Result B, and went left. This means in our timeline we went Left, and and what happened after happened. BUT, this action stemmed off many other timelines where someone went Right, or went back, or just stood there, or something else all together.
This would create multiple timelines where each choice stemmed off it's own new timeline and route. And then later in other choices by people stemmed their own. Give infinite timelines and almost creating a parallel web of timelines.
Example 2:
You're about to kill someone. A: Kill them. B: Don't kill them C: Many other choices. Say you don't kill them, another timeline you did kill them. Other timelines something else happened. And the life went on in each of them.
Now say you somehow went back and stopped something. Something else would take its place and give the same effect. Because in this timeline, it happened, and thus HAS to happen. UNLESS, you already replaced it with something happening.
So how does this tech work with that? It doesn't actually turn back the time, but replaces the area with the same area from another timeline.
So let's say you destroy a table. Or whatever. If you set the field to the area of the table destroyed, you could replace it with the table from the other timeline where it wasn't destroyed. Or even another one where something else could have happened. Whatever is in that area and field of effect. This would switch them out. The destroyed table would go to to the non destroyed timeline, and the non destroyed would come here. Restoring the table.
If that doesn't make sense.
We have two strings. String A named:Destroyed. String B named:Survived.
We field the table and cut its time away from string A Destroyed, and cut String B Survived, off their strings. We switch them, and somehow put them back together.
Now say it was a planet? If you have people, on A:Destroyed, that were destroyed and some survived. And people on B:Survived. There's two options. You have the field only designate the planet. Or have it include sentience as well. IF you have it include sentience. The people of Destroyed would also go to Survive and vice versa.
BUT since you switched out the worlds, they would not realize this. As their world is still destroyed, and the Survived is now survived. They would go on thinking they're still in the same Timeline from when it was created (When the world was destroyed.) So if some went to say hell, they would get switched to the newly created timelines hell. Nothing noticed, nothing lost. Same people. Same memories.
And so this doesn't nullify Orph's tech, since he brought time stream into it. I guess the stream is where all the timelines would be located. So by him going out of the time stream, he'd get out of the web as well.
