Twilight Sparkle was late. She was also screaming. Down the halls, up the stairs, she yelled at guards.

"Out of my way,please!",she called ahead. Guards jumped out of her way as she approached Luna's rooms. She spotted a brief flash of blue-black tail dart in front of her. Night Caster laughed as she passed her,"Better luck next time!"

She was in the door before Twilight could reply. Twilight approached the doors of Luna's rooms to see Luna herself waiting.

"Thou is late again, Twilight Sparkle",Luna said, her familiar way of speaking returning,"I hast been waiting for thine presence for an hour."

Night Caster smiled at Twilight evilly, slumped in one of the many midnight blue couches. She had grown beautifully. Almost a full-grown pony now. She was what, 15 years old? She was tall and lean but beautifully shaped and very pretty with cascading waves of hair, similar to Luna's but a straight blue-black color, only changing for a light purple streak that had appeared on her 13th birthday.

"I apologize. I got caught up in my court. Two ponies were fighting about- well never mind. Lets begin",said Twilight.

Luna turned to Night Caster,"And for thou too, just because thine battle training is fun doesn't mean thou may skip thine classes."

Night Caster nodded, smile gone. She got up and light fled the room except for the dark glow from the candles that lined the room. The three stood in a engraved circle, a star of power that Night Caster had made. The three released magic into the circle and the room was gone.

"Wha-", Night Caster began as she looked up to see a barren landscape before her.

"Nice of you to join me again", called out a dark voice.

Night Caster shuddered. She knew that voice, it was there when she first came here...

"You know me, Night. I was summoned by your power, back from the grave to properly teach you. That fool, Luna, can teach you nothing in that of real power", called the voice.

"LIAR!",shouted Night Caster.

The voice laughed and dark, red-green eyes appeared before her, purple mist radiating from them. The apparition stepped forward, revealing the form of King Sombra. He levitated a present to himself.

"I have a present for you, a late birthday present from your biggest fan",Sombra smiled.

"Where am I?",asked Night Caster.

"I do apologize, I didn't mean to drag you here. This is the Land of Eternal Damnation. My home. Its is in the Dimension of the Dead", said Sombra,"You can easily go home now, back to the Land of the Living, but I see you staring at the box."

Night Caster looked up from the darkly wrapped box up to Sombra.

"I pose no threat to you here. I cannot kill you, but I offer you power. The Dimension of the Dead isn't a place to take, but the Dimension of Eternal Darkness is.", said Sombra,"Please, open your present, if you wish afterward to leave, go ahead, I can't stop you."

Night Caster levitated the box over. She didn't know why she did, but it called to her. She slowly opened it and looked inside. It was a small crown, thorny and spiked, but the jewel in the center was amazing. Prismatic and black, the jewel sparkled in the dark light from the world around them. surrounding the center jewel was dark onyx and obsidian. It was evilly beautiful. Night Caster levitated it upward then set it back down.

"For you, a Princess of Darkness. Holding more power than Luna and me combined. You have a kingdom. Its in the Dimension of Darkness, similar to here, but much more powerful. I salvaged this crown from there in a brief visit, it took months to store that kind of power. You can rule, let me teach you",Sombra pleaded.

Night Caster stood still as he levitated the crown to her head. It felt right. Like it WAS meant for her.

"I must go, but I feel we'll meet again",Sombra said, smiling, but it was different, like a father's.

With that he was gone and Luna's room came back into focus.

"What's that?",asked Twilight.

Luna and Twilight were looking at the crown on her head.

"I'm a princess...",said Night Caster, still in shock from her meeting.

Luna looked at the crown than back to her student,"Where did you get that?"

"I don't know",she replied,"I was sent to a different dimension, the Dimension of the Dead, and King Sombra gave this to me, telling me I rule over the Dimension of Darkness."

Luna stared at the crown.

"Is it true?"

"Yes",Luna replied.

"Why didn't you tell me?",Night Caster was dumbfounded, her mentor lied to her.

"Let me answer your question with a question",said Luna, regaining a regal air,"What is darkness?"

"Well I-.... you see it's-.....uh....I don't know actually...",stumbled Night Caster.

Twilight was already sitting, still in shock over the whole thing, stoic and silent.

Luna motioned for her to sit.

Night Caster complied and a little light came into the room by regular candles.

"Darkness is the History of Nothing",Luna stated simply,"Darkness is the lack of light, correct?"

Night Caster nodded slowly.

"Well, what would Light be without darkness either?"

Night Caster just stared.

"Both are in equal balance, some refer this to as Yin Yang. My sister and I used to achieve this state, but since my banishment, our balance has fled to another. I believe you and my sister achieved it, quite brave of you to do that. I see now that the Princess of the Light Dimension and the Princess of the Dark Dimension are the true Yin Yang."

Night Caster gave her a quizzical look.

"Cadence, Twilight and I aren't true princesses. We are alicorns, yes, but not princesses, not like how princesses should be. My sister is the true princess of this dimension. How you got here, I still don't know. But, you are a princess."

"But-",Night Caster started.

"Silence, Morta!",shouted Luna, loosing it.

Night Caster's eyes widened. She knew that name. Was it hers? Then all the memories came back from her childhood. The Dimension of Darkness. Her parents' death. How she got here. Everything. Light fled the room and not even the anti-candles could penetrate the sucking darkness. Two dark eyes penetrated the rooms inky blackness. They were blue-black like the pony's hair with the pupils like slits, vibrant purple. And, as soon as it came, everything was gone, including Night Caster.

Author's Note

Sorry it took so long to post new chapter. I felt like I needed to jump ahead and bring back in Sombra, and Night Caster's childhood. Hope you guys like it.
