She is an alicorn with a power that is too powerful but not as powerful as Princess Celestia, her name is Luna, her hair in the middle is light blue and all the edges are too pale blue-purple, and her hair also has stars like Her tail, her cutie mark is a very shiny white moon and around it she has black spots simulating that she once became Nightmare Moon. She has a black necklace with a moon in the middle and her front and rear helmets are pale blue-black-purple. She also has a black tiara-crown. Her eyes are a somewhat bright turquoise-blue color.

The power it possesses is the lunar.
Its element is:
Moon.
Furthermore, her older sister is Celestia, her older sister has the power of the sun with the cutie mark of a sun. Princess Luna could become Nightmare Moon due to her great jealousy and bitterness, swearing that she would bring eternal night, but thanks to Celestia she was able to stop her with the power of the elements of harmony, so at the end of the battle she was sent to the Moon and Celestia was responsible for the Sun and Moon.

Luna still has a bit of a grudge against Celestia but she was able to control that a little.

Once upon a time...
In the magical kingdom of Equestria, two noble sisters reigned together and created harmony in the region... to do so, the eldest sister used her alicorn power to bring dawn, the youngest brought the moon to dusk, thus giving balance to the kingdom and its subjects, all varieties of ponies...
But over time the youngest became jealous. The ponies played on the day that the eldest gave them, but they slept in the beautiful night... but one fateful day the youngest refused to lower the moon to give way to the day. The older sister wanted to reason with her, but the youngest refused... who turned into a dark mare called Nightmare Moon, who swore that she would reign with the eternal night...
By thinking the greatest use that the ponies knew the elements of harmony used the magic of those elements, with those elements she defeated her sister taking her to the moon forever.
The eldest sister took charge of the Sun and the Moon, and harmony in Equestria has endured for generations...
