Because if I use it when I am glacial, I turn into "Gravitational" Blizzard. Not only do I have stronger ice powers, but I also earn gravity manipulation.

…ok why do you tell me this?

I wonder when I come in?

First, wanna know what gravitons are? Go to the link below:

https://en.m.wikipedia.org/wiki/Graviton

In the year 2874, people found a source of gravitons. A person made a gem with some of them. It was called "The gravity gem." He went to 2022 to put it into a museum. There it was called "The Gravitational Gem of 2874."

To fast i can’t see the weighting sorry. Also i have no idea how i fit in your story.
