The being that had taken over Derek's body did not waste any time. It knew that there were demons lurking in this world, and it wanted to kill them all.
It felt a burning rage inside, a primal instinct to destroy anything that threatened its existence.
It also felt a faint trace of Derek's memories, his emotions, his desires. But it did not care about them. It only used them as a tool, a means to an end.
It used Derek's knowledge of this world, his access to the library dimension, his author profession.
It entered the library dimension with a swift movement. It walked straight to the book that contained Derek's story, the one he had been writing for years.
It opened the book and scanned the pages with its glowing eyes. It saw that Derek had accumulated more than 3.5 million author points, a huge amount that could be used to improve his power.
