Unus Annus means one year in Latin. Unus Annus was also a YouTube channel created by Markiplier and CrankGameplays. That channel was only up for a year. Throughout the year they did stupid stuff together and they made a lot of people happy. Once that year was up though, they deleted everything of that channel. If you are a future generation reading this I am sorry you didn't get to experience or even know the channel Unus Annus. They made the channel in 2019 and ended it in 2020.

If you're looking this up, you're wasting your time. The clock reached the final hour long ago. Unus Annus was a beautiful piece of art in history that will forever be lost to time.

For those still mourning the loss, I have a few words from the painters of the magnificent piece.
"Don't cry because it's over, cry because it happened." -Unknown: Nov 13, 2020
Friend: Unus Annus is really gone, isn't it.

Me: It was destined to be this way. We knew this. Momento Mori, my friend.

Friend: Momento Mori.
