If you are a true fan, you will know it is run by Ethan Nestor and Mark Fischbach, I only said and a fan because i feel bad for Ethan's under recognition.

Unus Annus 

A mass fever dream that a large amount of the internet had over the course of the year 2020. We have no idea where it came from, but we do know that it's gone. People who have fallen into its grasps have all joined a cult based around it, but they claim it's not a cult. Memento Mori. Unus Annus.

Have you heard of Unus Annus? Oh no, don't tell me you're part of the cult as well?
