Very well, then.As a matter of fact, I actually combined the "Twilight's Kingdom" and "School Raze" arcs into a single scenario.Twilight, wanting to teach the magic of friendship to the whole world, opens the "Harmony Academy." Within days, one of the earliest students is none other than Cozy Glow. She's reserved and quiet, but the CMC manages to make her feel welcome. However, they notice that she has a rather devious side... Also, she acts extremely reclusive whenever she sees two friends having a spat, which occasionally happens. The strangest thing about her, though, is the fact that she always seems to be penning letters to an unknown recipient...Things start out well. But shortly after opening the school, she is summoned to the Crystal Empire by Cadance. She and the other princesses warn Team Harmony that an ancient villain from Equestria's past is due to return.The fiend is none other than Lord Tirek, a centaur warlord that stole other beings' magic... and in some cases, their very life essence! For months, he'd strike unsuspecting ponies and other creatures in order to satiate his growling hunger. The Elements of Harmony were truly stretched to their limit in order to seal the life-leeching beast away.Tirek was sealed in a massive cavern called the Dark Crypt. His body in a vegetative state, he was locked in a huge coffin, held shut by six enchanted keys. To keep evildoers from unleashing him again, these keys were scattered across Equestria's neighbor countries:Yakyakistan, the homeland of the YaksThe Mersea Strait, a tropical city-state and link between Shetlantis in the east ocean, and Seaquestria in the west oceanAntennea, the ancestral hive-home of ChangelingsThe DragonlandsMt. Aris, the home of HippogriffsGriffondale, the impoverished Griffon homelandSoon, Twilight and her friends learn that the Koopa Troop has been sighted in the very countries the keys were hidden in. There could only be one explanation: they were after the keys, planning to bring Tirek into their ranks. Team Harmony knew they had to stop them.With each kingdom they visit, Team Harmony adds one of the Student Six to their roster. While they embark on quests to prevent Tirek's return, Cozy Glow's experience at the academy begins to highlight the need for nonlinear thinking. As she studies friendship, she notices that many of the students seem to stick to one of the Mane 6's approach to a problem than an other. This sparks arguments, some of them quite severe. Close friends not willing to accept each other's viewpoints, even if they don't share them, brings down Cozy's mood quite far, enough so that she has flashbacks about two ponies fighting when she was little. All that, combined with scrutinizing visits from her uncle, Chancellor Neighsay, constantly makes her think that no natural friendship will last. She'd constantly be depressed and isolated. That is, until anytime a letter from her anonymous correspondent arrives...Before long, Discord stumbles across the school, noting the contentious nature of the students when the teachers aren't around. He meets Cozy Glow and agrees to join her in a chess game. Discord is flustered to lose chess to an 11-year-old Pegasus filly, but at the same time, he feels pride in her. The praise Cozy receives is encouraging, considering her last opponent was a sore loser and called her a "know-it-all freak."Discord is shown a textbook by Cozy, detailing the friendship lessons Twilight learned before she became a princess. Although admitting that the lessons are profound, he points out that they were written by a single pony, who learned it from a single friend. Discord tosses the book away, telling Cozy that not everypony will learn similar lessons the exact same way. He tells Cozy not to let a textbook tell her how to live her life.Following Discord's advice, Cozy Glow lets her textbooks collect dust while she investigates friendship on her own. From then on, she stops feeling sad whenever two foals would fight over which friendship lesson was "right;" she'd only scoff and move on. Eventually, she finds the very idea of a "school of friendship" absurd, ditching class to hang out with Discord and devise pranks. It was the ultimate catharsis for the young child.But when the team heads out for the final key, Cozy Glow witnesses a horrific breakup between two ponies in love. The reason? They disagreed over one of Rainbow Dash's friendship lessons. It was so intense, it gave Cozy the most vivid flashback ever, and she could only run out of the school in tears.When she meets Discord again, he immediately recognizes her shattered tears. That's when Cozy Glow decides to tell her why she sought out Twilight's school.A few weeks before she turned up in Ponyville, Cozy Glow was undergoing the painful experience of her parents falling out of love. Her professional, uptight father and her laid-back, lenient mother would disagree over things quite frequently. It only got worse, day by day, until she was sent to bed one night; she stayed up and listened as her parents were discussing divorce. When the conversation turned to which of the two would have custody of Cozy, she couldn't take it anymore. She snuck out of her bedroom, tying bedsheets together to make a rope out of her window. She ran away from home, trying to get as much distance between her and her parents as possible. She approached her uncle, Neighsay, who took her in, even though he was busy investigating Twilight's track record for recruiting ex-villains into her team.Just then, a final letter arrives from Cozy Glow's mysterious pen pal. It says he can give her the power to ensure no friendship ever breaks again. And so, with Discord's help, she makes a plan to get what was promised...Just before Team Harmony returns with the six keys, Chancellor Neighsay arrives for another snap inspection. He comes just in time to see a male Griffon beating up a young Unicorn filly, claiming Fluttershy's lessons are infinitely superior to Applejack's. Upon breaking up the fight, Neighsay is all too eager to file a scathing evaluation of the school. He reports to Twilight that, in addition to having students from countries that have had at least some conflict with Equestria in the past, students bicker over the friendship lessons being taught, and a little filly was viciously beaten for it. Therefore, he is closing down the school for good. He also confiscated the keys and takes them to Canterlot with him, bringing Cozy Glow along for the ride.Little does Neighsay know, however, that the "students" were just lifelike puppets, made to look real through magic. They were animated by Discord.Obviously, Twilight is devastated that a school meant to teach ponies and other creatures about friendship could turn into what it did. She laments the fact that she couldn't supervise the students more closely, wishing she and her friends weren't tied up making sure the keys didn't fall into their enemies' hands.In light of this, Alice Goldenfeather (OC by EStories) decides to share her opinion on the topic. She says that friendship is such a complex thing, trying to teach it in a classroom via textbooks and lectures doesn't give the proper experience. She says that, up to now, Team Harmony's members realized their friendship lessons more or less on their own, often with others' assistance. Friendship isn't a thing that's taught: it's found. That explanation causes Twilight to break down in front of her friends, apologizing for not realizing that. In truth, all she wanted was for other creatures to see how wonderful friendship truly is.As the group is wondering what to do, Rainbow Dash gets everyone's attention, noting how weird it seemed that Neighsay wanted to close a school that was at least TRYING to bring cultures into harmony, noting how bigoted he seemed towards non-ponies. Then, the team gets suspicious, wondering if Neighsay took the keys so the Koopa Troop could come by and grab them with no fuss. They wonder if he's helping their foes reawaken Tirek!So the gang sneaks out of Ponyville and quietly goes to Canterlot, having winged teammates carry non-flying ones through the sky and having magic-users levitate the rest with them. When they reach Neighsay's estate, they confront him on his reason for taking the keys, only for him to ask why Team Harmony collected them at all. He knows what they do; they're needed to free Lord Tirek from his prison. He took them because he feels he can't trust the entourage of a princess trying to bring "violent, shifty outsiders" into a land of peace.Team Harmony fights Neighsay. He's a surprisingly capable opponent with his wide arsenal of debilitating spells, but they defeat him. Starlight moves to acquire the keys from under a covered glass case... but something is wrong.THE CASE IS EMPTY.Neighsay and his unwitting home invaders search frantically. The cloaked stallion calls Cozy Glow down from her room; he recalls that she was curious about the seemingly useless artifacts....But Cozy doesn't show up. Neighsay calls once more. Again, no filly comes down. Naturally, he goes to the room himself. When he opens her door, he discovers to his horror that his niece has flown the coop! Everyone wonders where she could've gone while they search the room, where they discover the saddlebag filled with letters from her pen pal, known only as... "Mr. T..."That's when they see it all. Cozy Glow's pen pal was Lord Tirek himself. Reading his final letter, they see that his prison, the Dark Crypt, is located not far from where the condemned school is!The team doubles back to Ponyville and breaks into the school, only to find it filled with a purple mist and overrun by an army of life-sized, animated chess pieces, commanded by Cozy Glow. They find her in a tunnel dug beneath the building, chasing her all the way to Tirek's coffin. Mario, the Student Six, and the Cutie Mark Crusaders duke it out with the crazed rogue student, who is empowered by a jeweled pendant bearing the school's emblem.Even though she's beaten, Cozy manages to use her new power to trap her enemies in a shield while she limps to Tirek's coffin with the keys. She rants about how no friendship will ever fall through again, and how they should be thanking her.In a storm of dark clouds, Lord Tirek is freed. He takes a minute to reacclimatize himself, before noticing the proud filly beside him. Cozy Glow compliments him on his looks. Amused, he listens as she makes her request to help her ensure she can prevent friends from ever fighting.
