Unus Annus (lat. = One Year) was a project on YouTube made by Markiplier, as Annus, and Crankgameplays, as Unus. The reason behind the channel was to enjoy the time you had, live in the moment, and remember that everything comes to an end eventually. (Also worth noting: Memento Mori = Remember Death) They would upload every day for a year and delete the whole channel after the clock stops ticking. Memento Mori Unus Annus
