Her power centered around and depended on the abundance of water in the world. Luna was blessed by Neptune, the god of the sea and tides, and she could do miraculous things with water.
Some of the feats that she has performed with her element were seen as godly because of how impossible they seemed, but she was able to do them easily with her blessing. She could manipulate water down to the molecular level, tearing apart its structure, heating it, cooling it, shaping it, drawing it out from other things, and even using it as armor and weaponry. There hasn't been anything that she couldn't do with water yet, and people were always wondering what the limit of her power was.
She was yet to find out.
Luna sighed peacefully, and a puff of hot air wafted out from her body and heated up the moisture in the air to create more steam to fill the room. The man in the suit was slowly starting to sweat, but he did not show any reaction as he continued speaking.
