|“Yes. They won't just give us an edge over those nothing knights, they'll give us the edge over everything.”|
|— Monstrox to Jestro in "A Little Rusty"|
The Forbidden Powers were dark magical tablets created and used by Monstrox to spread evil and destruction across Knighton. They were eventually frozen in stone by Merlok and kept with Roguls. A sufficient amount of Forbidden Powers are able to awaken the Stone Colossus.
Prior to the series
The Forbidden Powers started out as dark, magical spells that were created by Monstrox so that he could become more powerful and cause great destruction across Knighton. But due to their level of power, Monstrox had to put the spells in small, black pendants and attached them to a chain bracelet around his wrist so he could contain them. As time passed, Monstrox began to become more interested in collecting the Forbidden Powers than using them.
In order to end his evil conquest, the Wizards' Council sent Merlok to stop Monstrox. Merlok confronted Monstrox in Brightwood Forest and Monstrox was defeated, causing him to drop his staff and the chain containing the Forbidden Powers in the process. As Merlok fell to his knees in shock of what had just transpired, the hand of Wanda Moorington gave the Powers to him.
With the Forbidden Powers now in his possession, Merlok attempted to destroy them so that no one could ever use them again for evil purposes. Unfortunately, they were too powerful, so he instead sealed them away in stone tablets and placed them with a stone guardian called a Rogul to defend them. He scattered them across the realm to make sure nobody would obtain all of them.
