About this item

This meticulously crafted masterwork is the ultimate culmination of the most grandiose, thought-provoking, and culture-defining ideas that the Gnawnian literary world has ever known. The elegantly written prose contained on these pages is so dangerously avant-garde that it narrowly straddles the line between genius and madness and as such, is far too unstable to be read by the general public. Only esteemed authors that have earned sufficient accolades for themselves are qualified to obtain and read this highly volatile but extremely valuable masterpiece.

This unstable item will reward powerful charms including Rainbow Spore charms as well as other useful and valuable items.
