Walking through the streets, a mysterious rabbit was listening to music. If one could listen closely, they'd hear music.

From the front, one could see this mysterious rabbit clearly.

They were walking towards the castle of friendship, a stride in their step; ignoring the ponies they saw on the way there. Soon, the rabbit was in the castle of friendship. Inside there, Twilight, Sombra, and Luna were talking about what Luna had encountered last night.

"I swear it was the weirdest thing..." Luna said.

"Why would this Guardian tell us to not trust The Observer?" Sombra asked.

"Because you shouldn't." a female voice said. The rabbit was in the doorway, earbuds out. One could hear the music coming from some earbuds she had in. "He's not who you think he is after all." The rabbit continued.

"This rabbit creature can talk?" Luna asked.

"Why is that always the first thing people notice about me? I swear, it's like I'm a walking celebrity or something." The rabbit said.

"Gee, doesn't that seem familiar?" Sombra asked, elbowing Twilight who giggled.

"Call me Score." The rabbit said before taking out something. "I'm simply here to get you in touch with my boss." She added before pressing something on the strange device she had. Suddenly things started becoming weird. "Don't be alarmed; we are simply passing the border between the conscious world and the unconscious world while this device is active." Score admitted. Soon things stopped being weird. And then a ball of light appeared.

"Greetings." A voice said before the ball of light took a solid form.

"That's him, that's The Guardian!" Luna said.

"I knew I'd meet you again, dreamwalker. Just not so soon. It's a pleasure to meet you, Twilight Sparkle and Sombra of course. The Guardian said.

"This is a strange phenomenon. It appears like we are still in my castle. But we aren't, are we?" Twilight asked. The guardian gave a hearty laugh.

A very wise young lady. It's refreshing to me." The Guardian said before he went towards Sombra.

"She is, isn't she?" Sombra asked. Suddenly something was drained from the stallion. "Hey! What did you just do?!" Sombra exclaimed but then blinked. "...Actually, what did you just do? I don't feel any different..." He added.

"All I did was remove my brother's taint from your body. Nothing more. Everything else is still the same. You still have the cutie mark you were given and still have your title. All I did was remove my brother's taint from your body." The Guardian said.

"Your brother is The Observer? Or at least the one saying that's who he is?" Twilight asked.

"His real name is The Omega. He was originally created by my father to destroy decayed worlds. And before you worry, a decayed world is one where all life is either extinct, or on the brink of total collapse. Your world is far from that. But something happened to my brother long ago and he went rogue, going against my father's wishes. So, me and my only other brother; The Darkness; confronted our sibling." The Guardian said.

"The Darkness? What was his job?" Luna asked.

"To make sure worlds had some evil in them. The Darkness was not evil himself. His job simply was to ensure the balance between good and evil. The battle the two of us had against The Omega was a hard fought one, but the two of us came out on top. However, before you ask to meet The Darkness, do not bother. While the battle ended in our favor, victory was bittersweet for us: The Darkness was hit by a last-minute desperation attack from The Omega; destroying his very soul." The Guardian said.

"Bastard." Sombra said.

"What happened after that?" Twilight asked.

"I contained The Omega to a specific area of the greater collection of multi-verses. That's happened to be where your world was cropped up on by The Creator and his two sons. I had every intention of preventing development here in this area. And now that there is development, I must do what I can to prevent The Omega from regaining his full strength." The Guardian said.

"If you need our help, don't be afraid to ask." Twilight said.

"Needing to ask for your help is exactly what I'm trying to avoid. Because if it comes to that, it may be too late to stop him." The guardian said.

"I gotta go." Score said. "I just got word that you know who is back." She added. the guardian nodded and things went back to normal normal.

"Where are you going? Whose back?" Twilight asked.

"My father." Score said before heading out.
