Butterfly Family

While the members differ between the AUs, there are several aspects that are common with all of them. One is that the Butterflies are the supreme or sovereign rulers of Mewni, hence why the Queen is known as “Queen of Mewni”, and that the Butterflies are matriarchal, ruled by women. The title is passed down to first born daughters, regardless if a boy(s) is born first, thou on rare occasions should a Queen not have a daughter then it gets passed to first born son. A canon example is Jushtin Butterfly, he was born first and an only child for 14 years and inherited the Royal Magic Wand and throne, but when his mother became pregnant with Solaria Butterfly he lost the right to the throne. Another common aspect is that when the princess turns 14 she inherits the wand.
