Princess Argent

Princess Argent is the ruler of the Shadow Realm and eternal enemy of Princess Solar and the Hooves of Light, but she is also her sister.

History
Princess Argent hails from the Shadow Realm, a dimension where darkness reigns supreme. As her worlds equilvalent to Princess Luna, she became the Nightmare Moon and spread darkness across the land. However, unlike her counterparts, she did not lose and instead became the new ruler of the land, but she did not do so without resistance. The Hooves of Light, lead by her dear sister, Princess Solar stood against her. Eventually, she was defeated by the heroes from another world who went looking for a filly named Summer but she did not stay down for long and instead entered their world instead.
