Lady Tirek and Twivine Sparkle walked through Canterlot in the dark of the night, where nopony would be able to see them and intervene with what they were up to.

Twivine had a different frame of mind than Lady Tirek. She didn't want to go around stripping ponies of their magic for the sake of gaining ultimate power. She knew what fate befell the original Lord Tirek, and she knew that Lady Tirek's fate may be similar, unless she does something different. 'What if she goes down Scorpan's path?' Twivine pondered. What if Lady Tirek manages to befriend a pony, and changes her ways? All those thoughts of a positive side to Lady Tirek flooded Twivine's mind. After all, if Lady Tirek was a combination of Twivine's magic and DNA, then surely she could be able to persuade Lady Tirek to become a good centaur. That way, she could avoid the fate of Lord Tirek.

Suddenly, Lady Tirek stopped in her path and looked up to the Canterlot Library, where a single window was illuminated with a bright light. "Looks like one pony is awake on this fine night, Twivine. Go up there, while I make my approach." Lady Tirek instructed Twivine, asserting her control over the former dark alicorn.

"Um...actually...is this really what you want to be doing with yourself, Lady Tirek?" Twivine asked, prompting a confused response from Lady Tirek.

"What do you mean, Twivine? This is what we've been striving for since your creation!" Lady Tirek replied, reminding Twivine of what her original intentions for Equestria were.

"Look...don't you think that maybe we should try something OTHER than what Lord Tirek wanted? I mean, don't you know what happened to him?" Twivine asked, once again trying to change Lady Tirek's mind on what she wanted to do.

Suddenly, Lady Tirek's face turned to once of slight frustration, but also had an unsettling grin. "Oh Twivine, you are so naïve. Of course I know what happened to Tirek, but I will not go down his path. Now, be a good little pony and introduce yourself to whoever lies on the other side of that window."

Twivine sighed and looked down. "Y-Yes, Lady Tirek..." she said as she walked into the library and up the staircase.

Within the library stood a single mare, Moondancer. Moondancer turned around and saw Twivine. Having never encountered Twivine Sparkle before, she made the initial mistake of confusing her for Twilight.

"Oh, hey Twilight, what brings you here?" Moondancer asked, happy that Twilight was paying her a visit once again. However, once Twivine stepped out of the shadows, she realised her mistake...sort of. "Whoa...your hair looks different. What did you do to it?"

Twivine looked toward the way she came in, hoping Lady Tirek wasn't close. "Look, Moondancer, I may look like Twilight...but I'm not who you think I am." She paused, taking in Moondancer's confused expression, then resumed. "My name is Twivine Sparkle, I'm Twilight Sparkle's dark twin, a-and you're about to meet my friend..." Twivine cut herself off due to Lady Tirek being in the room, behind Moondancer.

"H-Huh? What are you talking about, Twivine?" Moondancer quickly turned behind her, revealing Lady Tirek in all her glory.

"Hello, Moondancer. You must be a friend of Princess Twilight." Lady Tirek spoke, an evil grin streaking across her face.

"W-Who are you?!" Moondancer asked in fear. She stepped back, looking behind her to see Twivine looking on in shock and horror.

"You can call me...Lady Tirek. And you are just one of many." Lady Tirek spoke as she quickly began to drain the magic from Moondancer. She screamed out in pain and tried to escape, but couldn't escape the centaur's grasp. Eventually, she fell to the ground, exhausted ad completely drained of magic.

"I-I'm sorry...Moondancer..." Twivine softly apologised as Moondancer weakly walked down the staircase. Lady Tirek glew a bright orange briefly, before lifting the hood from her veil.

"Oh, this is just the start, Twivine. Soon, we will find every Unicorn, Pegasus and Earth Pony in Equestria, and after that, I will go after the alicorns!" Lady Tirek laughed as Twivine looked down at the ground again.

"What have I done...?"
