Kind, friendly, easy-going Earth Pony named Sandbar makes a deal with a yak named Yona, who was cursed to be a yak due to her personality. In exchange for his father's freedom, he had to stay with the yak in her castle for what should be the rest of his life. Living there alongside them are former ponies including Gallus, Smolder, Silverstream and Ocellus, who believe that Sandbar and the yak loving each other is the only way to get everything in the castle back to normal after an enchantress cursed it as punishment for Yona's bad personality.
However, there are more problems than what was mentioned before, as Sandbar's hometown is controlled by a manipulative mare Cozy Glow, who wants Sandbar to be part of her family through marriage, only because had that been fulfilled, she would gain more popularity and power.
As an Alternate Universe story, there are several differences made to the characters; The Young Six(with the exception of Sandbar) are ponies cursed to be creatures, and the whole group are as old as mares and stallions. Yona is mistress of the castle as queen. Cozy Glow is the same age as the Young Six.
This is my eighteenth overall story and the second to be an Alternate Universe story, therefore it is not linked with my other Friendship is Magic stories.
I actually would like to do a non-Alternate Universe Sandbar and Yona story, but since they had the MLP: FIM episode 'She's All Yak', I could not think of anything as good at the moment.
