A new multiverse roleplay

(Warning: This roleplay will have a huge amount of Kingdom Hearts flavor to it. I really like that game, just so you know)
.
In this roleplay there are a countless number of universes. For everyone who's born that is said to be of a pure heart, a Dimensional Being version of them is created in a universe called the Dimension of Creation. For example, if I'm born on Earth then another me is created in the Dimension of Creation at that time. Only one of me is created there, so if I'm born again in another alternate version of Earth, that doesn't count. The term "Pure Heart" can be used loosely. In the Dimension of Creation is a glowing ball of multicolored energy taking the place of the sun, and newly created Dimensional Beings fly out of the energy and land on one of twelve planets circling this Sphere of Creation. All of which are an equal distance away and positioned around it like a sphere from all "sides" and moving in orbits not hitting each other. On each planet is a Dimensional Portal to travel to other universes, but only beings known as Dimensional Heroes can use them. It's unknown how they have this power, but it's believed to be given from birth by how much of the energy they absorbed while being created inside the Sphere of Creation. Dimensional rifts can occur to send non Dimensional Heroes to other dimensions, but they're both random and unpredictable in the eyes of most people.
.
Now onto the plot. The Dimensional Beings have taken it upon themselves to be in charge of protecting the multiverse from those who can upset the balance. They send out Dimensional Heroes to help universes face bad guys known as Dimensional Eaters, absorbing energy from that universe's energy source similar to the Sphere of Creation, so they must be vanquished before that universe's Sphere of Creation type thing gets destroyed and causes what is known as a Dimensional Quake, a phenomenon that's thought to be able to tear apart the space-time continuum and destroy the entire multiverse if a large enough quake is to occur. While the inhabitants of a lot of universes are powerful enough to be able to kill Dimensional Eaters, only Dimensional Heroes who become Dimensional Masters are said to hold the power to defeat them once and for all. Helping the bad guys can also be inhabitants of the universes as well as bad guys with the power of Dimensional Heroes, who are unknown to the Dimensional Beings until their unexpected appearance near the start of the roleplay. I have a lot of plot twists thought up, one of which you might or might not already know involving the Dimensional Eaters.

Sounds exciting? During the course of this roleplay we can travel through universes that we make up or well known universes such as Middle Earth from Lord of the Rings, Final Fantasy, etc. Not only can we control the Dimensional Being version of your character, any universe where he/she/it was born in can also be controlled by you. In some universes, your character in that one can be some evil guy, super powerful, pathetic, etc. For example, my character can normally be a timid archer, but in another universe he's a space marine cutting down loads of enemies with a chainsaw.
