Rise Of The prince of nightmares

"...It is with discourage that I inform you that you and you're friends are needed once more. Signed Princess Luna of Equestria." Read twilight aloud so all six of them could hear the message."...You and your friends are to report to canterlot immediately  so we may inform you in person."Ended the letter."Wow, it must be serious if she has to summon us to canterlot just to tell us what is going on."Rainbowdash spoke first."Yes, it must be..." Twilight responded dully."There is a train headed to canterlot right now,we have a few minutes before it leaves,let's go."Twilight rushed.Soon after the train left with the mane six aboard, the wave of magic finally reached Ponyville in the form of a great shadow, blanketing the sky with darkness. " What is that!?!?!" Cried Twilight with raw fear in her voice. Then as out of nowhere a shadow burst from the darkness and slammed the train right off its tracks and sent it into the mountain. Destruction was everywhere, but no-one died. Twilight was the first to re-awaken from the accident, only to see a black alicorn. " Hello, Twilight Sparkle. Good to see you're alive. I'd rather kill you in a fight, but not right now, oh no, that would get rid of the fun, here..." Said this mysterious black alicorn as he showed a way to the castle through the caves." See what they have to say, goodbye." And with this he was consumed in darkness and slowly faded away." WAIT! WHO ARE YOU?" Twilight screamed as her full consciences  returned to her." Hehehe, My name is Darkflame." And with that, Darkflame faded into the midnight like darkness. After all her friends regained consciences  and saw that no-one was hurt, they headed inside the cavern path and kept going to see what was wrong with equestrian, But Twilight felt as though she already knew." Darkflame..." She mumbled. RainbowDash Immediately whipped her head around and blushed." Who?" she exclaimed trying not to sound surprised but failing greatly." I...err...umm....no-one, no-one at all.." Twilight covered up her encounter with this mysterious Alicorn with a strange grudge.
