Scrolls of Forbidden Spinjitzu

The Scroll of Forbidden Spinjitzu is a scroll of black paper that contains the dark secrets of Spinjitzu.

History
Sometime ago, when Wu and Garmadon were young, they were searching their father's library trying to find a cookbook to replace their regular meal of noodles. Then, Garmadon found a book called The Art of Broth, and a scroll fell out of it. Garmadon picked it up and said it was hot. He tried to read it, though Wu did not want to, and their father came in and took it from Garmadon. He told them never to touch the Scroll of Forbidden Spinjitzu, and ordered them to leave.

The next day, Garmadon went back to the library to find the scroll, because it was "calling" him. Wu did not tell their father, but followed his brother instead. Garmadon became frustrated when it was not there.

Wu wanted to know what secrets it held, though, not as much Garmadon. Eventually, years later, they found and read it. Later, Wu taped into the Book of Spinjitzu. Many years later, Wu realized the scroll was too powerful, and removed it.

It is unknown what secrets are kept in the Scroll of Forbidden Spinjitzu, and most likely will not be revealed.
