It hadn't been long after Celestia and the other princesses had been freed from Tartarus thanks to the Main Six using the Rainbow Power. But despite the battle being over, there was very little in terms of celebration. As soon as both teams of elements restored and the magic Tirek had stolen returned to where it belonged, Celestia locked herself away in her room and wept. Clutching onto the Optimus Prime plushie and the necklace Burst Stream had given her.
For some reason, Celestia could feel that Burst Stream wasn't as gone as everyone thought he was. And so, here she was in her room. Clutching the items that held the greatest sentiment from him. Hoping that somehow, there would be a sign that Burst Stream was still alive. She didn't have to wait long.
"Please. . . " Celestia sobbed. "Tell me that wherever you are, you're alright. . . " And as if answering her plea, the gem on the necklace Burst Stream had given her glowed with a brilliant, electric-blue light! Celestia was speechless at this, and wasted no time in putting the necklace on. A relieved smile on her face as she grasped it tightly. Unbeknownst to her, Nightmare Moon had been eavesdropping. And this news brought a small smile to the princess of dreams' face.
"Even when you're not here, you still manage to make the people you care about happy." Nightmare Moon said as she wiped a tear from her eyes as she left Celestia's door. "Perhaps, there's more room in your heart than I thought."
Meanwhile, in Unityville, Blitz Surge had arrived at the site where Burst Stream had made his last stand. Gazing at the spot intently.
"So. This is where you fell. Where your story ended. All you've done has led up to this. I thank you, brother." Blitz Surge said with a smirk. "For your end is the herald of my beginning. You saved me the trouble of eliminating you myself. Now, a true hero will rise forth. Things will be as they should be. Now that power's time has ended, justice will rise. . . "
