"The darkness welcomed me when no pony would, and I will do what I must to protect it!"
The last thing he remembered was the white void of the Limbo, a place where he should have been sealed away for all eternity according to Starswirl…but he was in Pone Henge again, he wasn't sure how much time had passed since his imprisonment, but he could tell it was a lot.
"What…how are we here?" Stygian asked, he could feel the presence of the other being who inhabited his body "I̴ ̴d̵o̶n̶'̴t̷ ̶k̸n̷o̴w̷,̴ ̵i̶'̸m̶ ̷n̵o̵t̶ ̶e̷v̶e̶n̶ ̵s̷u̷r̶e̵ ̷h̵o̷w̵ ̶w̶e̷ ̴m̵a̵n̸a̸g̸e̸d̸ ̷t̴o̵ ̴e̸s̶c̴a̸p̶e̴ ̸f̵r̵o̴m̷ ̴t̵h̶a̸t̷ ̷h̴o̶r̶r̸i̵d̸ ̶p̷l̶a̴c̸e̴"̸"
In that moment, a dark figure appeared before Stygian "Welcome back, i have summoned you again" "Who are you?" Nightmare Moon chuckled at that "Oh you don't even remember your own "mother"? The one who made the dark form that is part of you?" "What are you talking abou-I̵t̷'̴s̸ ̸t̶r̵u̸e̵,̵ ̵s̷h̸e̸ ̴i̶s̶ ̸m̵y̷ ̷c̷r̶e̶a̶t̵o̸r̷,̵ ̷w̶h̶a̷t̵ ̴y̸o̵u̴ ̵p̴o̸n̴i̵e̴s̴ ̷c̸a̵l̵l̵ ̵"̶m̸o̶t̴h̴e̷r̷"̷,̷ ̴w̸e̷ ̷m̵u̶s̶t̷ ̷o̸b̸e̴y̵ ̷h̷e̸r̷.
"You must be tired, come, i have an special place just for you" Her aquamarine eyes glowed with malice"after you and your powers have fully recovered you must do a very special job for me"

Here is the origin of "Nightmare Moon"fav.me/ddxhird and her true form Somnum, and in here fav.me/ddt35ac i said that Nightmare Moon took Stygian as her "son", why? because of i was inspired by thia bit from the wikia 'According to Applejack, when Nightmare Moon was banished to the moon, traces of her dark magic stayed behind. When night falls on the Castle of the Two Sisters, that dark magic takes the form of the Pony of Shadows."
So, Nightmare Moon/ Somnum traces of magic resulted in a being weaker than her, who couldn't fully possess the body of it's vessel (like NMM does, since here she is just Luna's body controlled by Somnum) instead they form some kind of "bond" with the vessel in which both of them control the body. Afterbeign exiled Stygian found the entity, who he nicknamed Styx, and bonded with him, when Styx/Pony of shadows is in control, his eyes turn white.
Oh btw Stygian is aged up in this AU, in my HC he is 18, but here he is 25.
