Muktionary

The Muktionary was the original grand holy text of the Muk. It was created and given to Muk-Pope Joseph I at the start of the universe to add to.

Creation
When the Mukness created the universe he wrote the Muktionary to record everything he created. Unfortunately, he simply was to occupied with creating the universe that he handed the task over to his Muk-Pope, Joseph I. Joseph I has since been adding constantly as the Mukness creates more and more. In fact in the time it took you to read this section, over 5 billion new things have been created.

Second volume
When the first Muktionary ran out of pages (at page 567592376452387456876087465234548971123461087307) Joseph I knew it was time for a knew Muktionary so he created a second volume and imbued it with special Mukpower so it could have limitless pages.
