The Pyramid was a Nightmare Lord who had dealt with Wizards on many occasions and was very clear about their preferences.
These strange creatures from Otherworld had little interest in most things in the Nightmare World.
Only a few items, such as Nightmare Artifacts, Nightmare Artifact Embryos, and a handful of other extremely valuable things, could pique their interest.
However, after dealing with Wizards for a long time, the Pyramid gradually realized that these beings, known as Wizards, had an extraordinary craving for "knowledge."
For Wizards, some techniques of using the Power of Nightmare or the summary of understanding of certain things were even more attractive than hundreds of thousands of strands of the Power of Nightmare.
In the past, having grasped this fact, the Pyramid had made numerous deals with Wizards using knowledge.
This had allowed his territory to expand rapidly.
