In the distant past, Etaina was the oldest of the original Key Trio. She represented the purple key which stood for power and could grant untold strength to those who wielded it. Etaina was not the friendliest of her siblings, and was always jealous of the attention her sister and brother was getting when they were out plowing the fields. She wanted more power! What she had, even as an Alicorn, was just not enough.
One day she went into the village that her and her siblings protected and snuck into the room where they had kept a beast sealed for as long as the villagers remembered. She bargained with the beast; If they gave her more power she would free them from their imprisonment. The beast accepted her offer, but the power was more than she could handle and she was transformed into a draconequus and losing her link to the key she had stood for. No longer was she the Alicorn of power. She had betrayed the village.
Her remaining siblings could not face off against the beast as easily as they once did now that their oldest sister had joined forces with it. The battle was a losing one. When the dust settled, the village was in ruin and the key trio had disappeared while the beast had escaped and went into hiding.
In time, however, the key trio would return. But no longer in their original forms. Or their original names. And now with someone new for them to protect.
