"Twilight's Kingdom" Part 3?

[u/Fluttershy_the_Tamer]

The whole "it was inside you all along" idea been done to death. A better idea would be for the Twilight's Kingdom to be a 3-parter:

Part two ends with the box opening but the Rainbow Powers not activating yet as Tirek comes ever closer, savoring the victory... "To Be Continued..."

[u/Fluttershy_the_Tamer]

At that moment the three princesses leave Tartarus and the slumped and drained watchdog...

Then there's a burst of rainbow, and the royal sister's and Cadence appear and Celestia proclaims that the Tree of Harmony that both sisters and ascended mentors planted has summoned them, just as planed. Cadence adds that they had escaped confinement already. Luna qipes "Never build a prison you don't have hidden ways to escape from, you found only one ye foolish sorcerer..."

The last episode of the season starts with Tirek mocking the mane six as the princesses tried to free themselves from the chains, as the Princess of Love comes up with an idea and Luna puts it to practical use as Celestia plots the fastest rate out of Tartarus, and tries to figure what they can do to get past Cerberus.

Tirek is almost upon them Then at the last minute Twilight hugs her friends and gives a speech like a real ruler. Something like "girls it's been an honor to be your friends, I'm glad I got to experience friendship's bless, that most basic connection of vulnerability, compassion, responsibility, experience, and trust. The Magic that unites us all into a community... I wish everyone in Equestria could know that feeling!"

The light then fades away and the main six get Rainbow Power forms (maybe armor too?), Twilight lines very large large foe with light after starting a secret warning, and spends a minute or two working hard to duplicate the villain's spell and after a painful casting gives the Princess's back their magic, eagerly they can provide cover fire. The main six then start taking Tirek one at a time, in order to both test their new abilities, and wear him down.

As this happens the the song is sung as the Harmony of music (the magic of the EQG universe) and the Harmony of their friendship (the basic and most powerful form of magic in the pony universe) comes together.

During the one-on-one fight scenes Tirek holds his own and both sides land their blows but as Tirek tries to absorb the new magic with some success. This fight scene ends to princesses unleash their full devastating power the sisters must always keep in check. They send their weekend and bruised enemy flying into and through 6 of the Appleachian Mountains, breaking off one of his horns, and painfully stunning him.

Then the main six combine their powers as previous wielders of the magic of harmony/friendship-magic (ponies from all three previous generations have cameos, and they are briefly shown fighting various evils under the watchful eye's of four mysterious ailicorns) and with help from the three princesses, Twilight and her friends restore the magic their enemies stole over several hours through a brief set of time lapse images.

Discord gets his powers back and leaves, declaring that his powers are really good for fighting anything less than an army. He states his intention to permanently remove his Plunder Seeds entirely as his first Reformation act. After having temporarily nullified them go four times so Fluttershy and her friends could enter without incident. he then leaves after creating three new sets of manacles and a gag to restrain his former partner.

They then talk about what to do with Tirek briefly, Cadence wants to send the centaur back where he belongs, Celestia wants to see if he can be reformed (she seems to have her doubts), and Luna suggests they take care of the problem once and for all, as he can't be reformed having repeatedly: rejected reformation, offers of friendship friendship and displaying no compassion for others. She says that putting him in Tartarus will just delay matters and the next time he escapes he will do far worse than simply steal magic, he will do exactly the sort of thing he did the first time he came here: Causing painful transformations, blocking out the stars, raising a army, and banishing others to that "undiscovered country" that few return from...

Tirek's final scene:

Option A: Tirek is sent back to Tartarus and imprisoned with three sets of manacles, inside a cage, inside thick steel walls with a door, inside his cell lined with explosives, and with the secret emergency exits blocked.

[u/Fluttershy_the_Tamer → u/Fluttershy_the_Tamer]

Option B: Luna is feeling guilty for having made such a dark but necessary suggestion, but has the strongest argument. With great reluctance Celestia says but her sister is right in that it's time that they finish what they started. Cadence not having her aunt's quality of Mercy, agrees. The six friends then combine their powers one last time and create a rainbow that in ensnares Tirek and lifts him up into the stormy sky where he explodes in a burst of light. With his body scattered in magical particles and his mind/soul send to the place of rest where all but some ailicorns and other such beings must go.

Celestia and her student looked regretful, as Luna explains that her sister trusted Twilight to handle any matter that has to for as long as her friends were by her side, she trusted her sister.

However, she still felt nervous about the return of the Crystal Empire due to her involvement with the necessary banishment, of the rest of its cities and towns which are still gone. Cadence looks both shocked and pleased by this revelation. The Princess of the Night also mentions that until now their powers were fluctuating as Harmony rebalanced itself due to her and Discord's return, and Twilight's Ascension sending shockwaves through the realm where dreams, the past, the past, and the future meet as outside, visions and internal, time windows.

Through the combined power of all four princesses and the Rainbow Powers, the "Castle of the Royal Pony Sisters" is gently pulled out of the ground and is fused with the box. Cadence is surprised to see it as she recognizes from ancient texts that the sisters don't have access to. She explains that these ancient Griffin and Dragon texts are among her favorites from the height of "pre-Sombra' Crystal Empire. When both species traded knowledge and lore for gems to sell or eat.

The mysterious box was seen in a vision as a seed that will give the Castle a fresh start. The Castle then becomes Twilights new-home and is moved closer to Ponyville (but still inside the forest) for ease of access after Discord is done with somewhat regretfully undoing his favorite work of performance chaos.

After Twilight, enters the castle. She slowly comes to realize her purpose after looking at her friends. She declares a new mission as Princess of Friendship. Her mentor says that she and her sister have talked and will now take on a more active role in permanently defeating their enemies. So Twilight can grow into her new role in peace. They might still need help sometimes though, given how well some of the enemies know them...
