Seaquestria

Seaquestria is an underwater kingdom in the world of Equestria outside the reach of pony territory, and a capital located within a sea cave directly beneath Mount Aris, a colony of pure hippogriffs who descended from Equestrian pony-griffin interbreeding, and thus granted them Equestrian purity. Since the city of Mount Aris known as Hippogrifia was ravaged by The Storm King, the hippogriff subjects, including their leader Queen Novo, retreated underwater with their allies, seaponies, which are aquatic ponies and cousins of merponies who are more in tune with sea magic from the Alicorn Goddess of the Sea Princess Maricolous, whose soul is contained within a Pearl under the protection of Seaquestria, and currently looked after by Novo and her seapony-turned hippogriff subjects, as Novo was a protégé of the seaponies' previous ruler, Queen Abysswish, who died after being turned into sea foam thanks to a fight against Storm King, leaving her to take up the mantle as leader, keeping her subjects in isolation since then until The Mane Six came in. Novo's daughter, Princess Skystar, lead them to a hidden cave pool entrance which is the best accessible way to Seaquestria to land-dwelling beings, and welcomed them until Twilight Sparkle, desperate to save Equestria after so much pain she's been through to where she had a hard time trusting her own friends, convinces them to distract the seaponies while she attempts to steal the Pearl of Transformation, which uses magic from Maricolous to transform land creatures into sea creatures. However, the security system gave her away, and they were banished as puishment. Though hostilities were made from this choice from both Twilight and Novo and thus damaging their social lives, they eventually worked everything out to stop Storm King a second time thanks to being resurrected by his family, The Storm Clan. Seaquestria is revealed to have been a distant ally to other underwater societies like Equantica, among others, and they aid each other, especially since the Equestrian ocean is full of threats like Squirk, a kraken scourge who almost flooded the world to dominate it until his Flashstone was split and taken by the seaponies. Outside the sea cave castle, the seas are filled with temples and houses with elegant, vivid, and colorful underwater cities, gardens, and so on, and yet it is still a minor seapony city.
