Tja O̊s̖h̗ro

Tja O̊s̖h̗ro is the mightiest of its kind. Legend has it whenever this Lordfin descends into the realm from up-high in the land of the Greatfins, that hurricane winds will buffet the seas, and that all storms will be abated as they hear its call and bend their knee to their lord, the Breaker of the Sky, the Ancient Storm, the Fork of the Gods.
Tja O̊s̖h̗ro undoubtedly has their own name given they are such an illustrious beast, but to the people of the Songlands, it is known only as Tja O̊s̖h̗ro, Cloudbreaker, and its various titles.
To the Songlands, Tja O̊s̖h̗ro first became real during the Conquering of the Songlands where their rider Isso̊ Áslá The Golden Conqueror brought his host upon the Songlands.
Long ago, during the War of Lights, it is said that Tja O̊s̖h̗ro descended upon the world bearing its rider, descendant of Tja O̊s̖h̗ro's original rider Isso̊ Áslá The Golden Conqueror. In the skies above the Songlands, Tja O̊s̖h̗ro could be heard from miles away, raging a great tempest against the Prismatics and their conquest of the world.
One such fight involved a fight with a great dragon infused with power of Prisma. At the feat of this great and terrible beast, the world changed as it willed; Turning seas into sand, the sky into water, or grass into lava. Their battle created the lights of winter, as Tja O̊s̖h̗ro was forced to summon a roiling tempest in the frozen north, a quarter the size of the known world to imprison it.
What became of Tja O̊s̖h̗ro is unknown for after the battle, its rider the Diamond King returned with no Tja O̊s̖h̗ro.
