Dimensionless

If you know anything about how the system of dimensions works, you would know that there may be a dimension in which you may be a lonely bar tender, or another in which you're a genius crime investigator, or another in which you don't exist, or another, or another......so on.
What you did not know is that there are some.... a handful perhaps, who exist only in one dimension. They're born not belonging to any dimension. This means that it's not only one dimension they exist in, but they can exist in any dimension they want at any point of time.
Most of these, okay, all of these people have the power to detect the presence of an opening to another dimension and travel through space and time and dimensions. They can feel the presence of another dimension when they pass by. (okay it's not as easy as that! But there's no doubt that they don't have a special ability that the rest of us don't or haven't been able to develop.)
Such people are called "Wanderers." There are about 10 wanderers known to us so far. Some are do-gooders. One of them tried to make people he met fit in and if they didn't fit in in their dimension, he'd take them to another.Some on the other hand were quite the evil geniuses. Take Wander for example (He's changed his name to that. Nobody knows his real name.) At first, he used to steal money from large corporate banks and sneak off to another dimension. But, his mind powers developed (as they do for Wanderers) to such an extent that he tried to steal planets in to another dimension where he planned to start his very own galactic empire. It may have worked too and Ishnaa may not have been able to stop him if it weren't for one of those planets spinning out of orbit and on a collision course for another because he miscalculated the gravitational force. The only way to stop that was to turn back time.... which Wander managed to do(because he isn't that evil!). Henceforth, Wander was kept on an isolated planet where people occasionally came to visit him so he doesn't go completely mad(if you know what i'm saying). This is where Ishnaa meets him.
