These are of course not canon and are only my interpretation.
In my Hippogriffs headcanons (here Hippogriffs-HC) i said that the Storm King invaded Mount Aeris 100 years ago, so, did the Storm King lived that long? The answer is, the Storm King brand it’s a family business! “Storm King it’s only a title that they pass with the crown.
From left to right:
Altocumulus, the mad storm. Cumulonimbus the dark cloud. Stratus the freezing breeze, the father of the current Storm King, Cirrus.
The great-grandmas of Sapphire Shores and Mrs Paleo (Pearly Shores): Espuma and Marine Shelley.
Espuma was a pure seapony, born before the truce between the Hippogriffs and her species, she was captured before the attack of Mount Aeris by Marine’s father, a pirate. She was given to Marine as a “gift”, Marine was a researcher of aquatic lifeforms, and was terrified when her father gave her Espuma. Marine helped Espuma escape in the middle of the night. After many years, they found each other again.
They had a daughter, Calypso, a singer that performed in Monacolt, she married a stallion called Jolly Waves and they had a daughter,Clear Aqua. Clear Aqua married a Monacolt noble, Diamond Shores, and had Sapphire and Pearly. Pearly married Riposte Paleo (who also had some pirate relatives in his family tree) and had little Petunia. Petunia is super spoiled by her aunt.
“Auntie Sapphire!” “I’ve missed you so much dear! How is my little pufferfish?”
