What would you do if you only had a year left to live? Would you squander the time you were given? Or would you make every second count?
Unus Annus was a joint YouTube channel created and run by Mark Fischbach and Ethan Nestor-Darling. The two did a variety of activities on the channel, uploading one episode per day, while steering clear of normal gaming videos they are known for. Ethan represented the "Unus," while Mark represented the "Annus" persona.
