If I ever were to make this an actual thing, it wouldn't be a book.

It'd be a comic.

In that comic, it would explain that their are six gemstones that posses power.

The Red Gem - Fire/Heat
The Blue Gem - Water/Ice
The Green Gem - Earth/Nature
The Yellow Gem - Air/Lightning
The Black Gem - Darkness/Death
The White Gem - Light/Life

The first one that Iv finds, is the fire one, which makes her the famous Scarlet Phoenix

The red gem gives her the ability to control fire, lava, heat, etc. It also gives her wings and the ability to fly.

But as the comic goes on, she finds the other gems.

The blue gem lets her control water, ice, cold, etc. It also gives her these special ice skates which give her super speed and let her skate over water.

The green gem gives her the ability to control the ground, earth, nature, etc. It also gives her a huge boost in super strength.

The yellow gem gives her the ability to control the wind, lightning, electricity, etc. It also lets her teleport, or 'zap' around anywhere that there's an electric current.

The white and black gems are the ones that balance the good and bad of the world, and both can make any creature have unimaginable power, whether for food or bad.

Also, the four elemental gems can be used with others. :3

So leave in the comments if there's any combination you'd like to see!

Red/Blue
Red/Green
Green/Yellow
