Aliens from Sedna

What are them ?
The Aliens from Sedna are a race of extraterrestrial beings who originate from a distant tiny speck of dust orbiting a little yellow star.

They're known for being extremely good at lying. This might be a lie.

GrimPotato is definitely not one of them.

That wasn't a lie.

History
Five thousand years ago, there were two Aliens from Sedna. They did stuff, and generated the rest of their kind.

A thousand years ago, they changed their eating habits and started feisting on meat. That's why they're so dangerous.

995 years ago, an Alien from Sedna called Sônia Abrão took over the little world. That hag usurped the throne from the original Aliens from Sedna, sending them to a hellhole of a place called Santa Rosa dos Purus, a city they live in to this day.

Sônia Abrão constantly seeks the expansion of her empire. So, 200 years ago, she fled to a planet called Earth, where she maintains a shady conspirational organization which fills people's minds with subliminal messages about the Aliens from Sedna empire. The Mushroom Kingdom has a deep hatred for Aliens from Sedna. The reasons are currently unknown, but it is mostly because some people think Peach could be one of them.
