Create a Golden Plaza where the prince of a very powerful race called Eternals

Create a Golden Plaza where the prince of a very powerful race called Eternals, son of the King of Darkness and the Queen of Light, is creating a new universe with his Violet power, a forbidden power that his parents didn't like him to have. He wields a purple power lance, which holds the purple Infinity Gem, the Gem of Power. His guardian animals, a purple wolf and a purple Chinese dragon, accompany him in this new realm.
