There was a time where avians lived peacefully.

Sadly, a day fell upon on the species when other mythical beings hunted them down relentlessly.

The few remaining went into hiding and an avian rose up to become king over the few.

Years later, they soon repopulated.

The gods from above decided to bless the species so that a male avian will be born with a womb.

That male was to be married Hyujin, one of the descendants of the fallen king, but the chosen male hasn't been found, yet.
