An odd phenomenon.

It exists everywhere in time but it's form was gained when the sun of the future granted a wish.

A wish granted in the future, that has affected time itself.

It simply has body since multiple timelines have been removed because of the wish. It made time focused on the timelines that the future moon is alive in both the past and present. Timelines of the new moon being dead doesn't exist. A wish granted out of love. The future, that was previously predictable by strings, doesn't exist anymore. Everything exists in the moment.

Due to this, time was condensed down to where she was able to have a body again. 

It only talks to the new moon and the new sun, occasionally offering advice but more excited for what's to come.

As the wish the new sun granted has made a future it cannot see.

Previously a "Time-eater", a planet that has began eating time itself. 

After a long time she has become what she eats and is now time itself in Eden. Multiple instances of Time exists. Each universe has their own version of Time.

It's a common occurrence for planets, also known to others as demons, to cause destruction. Their true forms often monstrous and inhuman that stop at nothing to consume and destroy. She was from a different sky than Eden. Most planets come as groups, family. She was the only one in her sky. She had met other planets such as Virion and his kin. She may have known her a bit too well as being one of the many past romantic relationships he had. In the end she wandered the worlds by herself.

 Before Eden was even a world, a physical place. There was nothing to eat. 

She was trapped, to others she has disappeared from existence. Trapped in the place of nonexistence.

She ate her own body and then time and then became Time. 

It was so long before Eden had become a physical realm. 

 To others it was dead, to the world it was more alive than ever. 

The Wish of The Future was granted. 

Many things happened because of that. So many things could be explained because of that moment.

It still didn't have a physical body but it was aware. It was awake. It was alive.

The in-between of all the pieces of Eden it was awake in. That's what the new sun called it "Mirror realm" the place of nonexistence. Since Time was in here it was causing disturbances on the outside because of Time not being omnipotent anymore. The new sun offered a solution, a body. In a form of an amulet the rest of the planets, now called angels, have.

So that's where she is now.
