Hi, this mod adds two new books to the game, they both change 3 attributes of each individual player who holds them, Size, Gravity, and Speed.
The first book is known as the Liber Mutatoris Mundi (The book of the world changer) and the second brings the Liber Mutatoris Galaxiae (The book of the galaxy changer), LMG is greater than the LMM but needs the LMM to be made
