All Hail Twilight

After driving off the real Grogar, Twilight and her older friends decide to share the story of how she became a full-fledged Alicorn to the Lodgers and her new student Luster Dawn, as in how she inherited the godly power of the head of all Alicorn Gods, Queen Philosophia. She found the soul of the goddess of friendship herself after defeating Tirek and Chrysalis (Cozy Glow only in alternate timeline) and dealing with Cozy Glow and Backgammon. She ends up meeting a new more powerful threat than Grogar: Judas, a Thanos-esque Panan 10x the conqueror the Storm King is, and the most serious threat the Mane Heroes have ever faced. He conquers Equestria better than any other threat and gives Twilight a challenge as the ruler of Equestria. With Judas proving too good for them, Twilight has to find the soul of Queen Philosophia, as her soul is being sought by Judas and his four Odontotyrannos foot soldiers, Ivory Crack, Sheen Obsidian, Tyranna Yesteryear, and Volgue Forge. Thus they must get to the soul before Judas does.
