McOS is split up into multiple different times:
Classic is all of the events before the recreation of the original MaowcraftOS-Terminal server, it did not have any major villains or enemies, and thus far did not have any story arcs.
Classic did not include any World elements and was only one main server.
- The Classic period also extra users who later on left because of problems with the server during the Classic period.
- Originally, the managing account of the entire Classic period was a discord account labeled as 'MaowcraftOS', a side account of the now main managing account Maowcraft.
- The access to the main server was only available after doing a large quest where you must re-upload files to a bot.
- The Classic period was inspired by another roleplay known as AquaOS.
