Daily Punch 10-25-22 Eternal Tablet tome for Call of Cthulhu 7th Ed

I have an idea for something new and fun. Let’s throw this up to the players!

Eternal Tablet
English, by unkown author found in 1926

This tablet was found in a mine in 1926. the author is unknow, but the most remarkable fact is this two sided stone tablet never shows the same text. Each time the tablet is turned over, a new page of text is seen on the tablet reveling more debauchery and horrible knowledge with each revolution of the tablet.
France. Only one copy is known to exist and it has been lost since 1933.
