Future Eagan Au
This is a look at the future of the universe of Eagan, as I said Fayna becomes queen, her mother advises her , her daughter and Caleb (a starco) being the first princess Lucitor-Butterfly, Fayna controls both kingdoms after the end of the war, Star and Marco retreated to earth after their children lost the war and Caleb decided to marry Fayna, The Lucitor now have more control of Mewnie and Lucitor Castle was raised to earth taking the place of the old castle Butterfly
Fayna is a great queen, she has rebuilt everything since the war and tries to teach her daughter the best she can so that everyone can be seen with equal, mewnians, demons and monsters, no one will suffer the pain of war like she and her family ,Caleb serves as a support, but he has allowed his wife to have full control by maintaining the matriarchal tradition in Mewnie
The little one will inherit two Wands the Lucitor Wand created by Fayna and the classic wand of the Butterfly being the first queen in history with two wands , she has more demonic features, but was born without horns, and inherited the blonde hair and blue eyes of her grandmother Star
In case you are asked, Eagan has no children, no plans to have them soon (he has discovered that he ages slowly because almost all of his genetics is from her mother, so he is enjoying his adulthood, physically it continues as when he was 27)
