In my Age of Equestria universe, Gusty the Great is Clover the Clever's cousin and she was the brave unicorn warrior who recently had a divorce with Starlight Glimmer's ancestor, Vesper Shine, the unicorn stallion who led a group of corrupt pony officials to attack the City of Tambelon before he killed Grogar's wife, Rosanna, before Grogar eventually murdered Vesper Shine to gain revenge. Gusty the Great became close friends with Starswirl the Bearded and when she investigated the deaths and disappearances of unicorns, pegasi, and earth ponies, she soon discovered that Emperor Grogar was the one responsible for the crime scenes. She confronted Grogar alongside Starswirl before they immediately fought against the mad ram while freeing the ponies who were captured for cruel experiments. Eventually, Starswirl and Gusty exposed Grogar's villainy in front of the citizens of Tambelon at the square before Avalor the Wise came.

As punishment for harming ponies out of hate, Avalor casted Grogar out into exile to spend the rest of his days in the wilderness at the Neather Lands and Grogar declares Starswirl a traitor & friend-turned-enemy and Gusty an enemy before the evil ram was banished from the City of Tambelon for secretly studying Necromancy & Dark Magic and for capturing and murdering ponies. Gusty the Great and Starswirl the Bearded developed their relationship even further before they fell in love with each other, despite the fact that Starswirl the Bearded was older than Gusty the Great. Whenever Grogar was out of the shadows to prey on ponies, Gusty and her unicorn warriors would hunt him down, fight him and drive him back to the darkness from whence he came. A couple months later, Gusty gave birth to twins whom she and her lover, Starswirl, named Stellar Nebula and Mystic Spell.

When Emperor Grogar returned for revenge, Starswirl and the Pillars went to defend both Equestria and Princess Celestia and Luna while Gusty stayed in her home with her son and daughter. Years later after Grogar had been imprisoned, Stygian became The Pony of Shadows before Starswirl and the Pillars casted a spell which trapped them all into limbo. Gusty the Great was devastated after her lover had vanished into thin air and was never seen again and when she died, the ponies of Equestria built a statue in honor of her. No pony knows if there exists the descendent of Gusty the Great and Starswirl the Bearded, but there had been a theory that Twilight Sparkle, Sunset Shimmer and Trixie Lulamoon could be the missing descendents of the legendary unicorns in Equestrian history.
