For The Hippogriffs

The Mane Heroes are invited to Hippogriffinstone, the homeland of pure hippogriffs, along with many seapony allies, by it's ruler, King Nephostratus, to wash away all the awkwardness that called for the summit Celestia authorized after the events of the movie, as he helps them plan a Festival with his daughter, Princess Ocheasha, and many new hippogriff friends. However, there is already a new problem in the form of not just the returning Storm King, as he escaped his predicament with Abysmalwish after her defeat, but the one who found him afterwards, a brother of Wind King named The Weather King, who was one of the many defects who still stuck close to the Clan, though is like both Iago and Latifier in personality, but is still as menacing as Storm King. Worst of all, the two have gained a new Tempest in the form of a tormented hippogriff named Corona Glory, whose PTSD from fighting against Storm King allowed her to become a sleeper agent with just as much ferocity and evenly-matched skill as Tempest, this time with no repercussions. Now the two plan to destroy Hippogriffinstone and chase the heroes underwater and off to nearby areas, and now they must avoid Weather King's stormy reach at every turn, and find a way to deal with him once and for all.
