How though
Nior had to rack his brain because technically he could go on an adventure he had the money, the time, the strength. But you see it was really the last one which set him back because he wasn't just strong "enough." He was TOO strong to the point that if he even went on an adventure nothing would pose him a challenge at all.
Even that dragon he had just watched Kald and his party struggle against and defeat he could've took it out with a snap of his fingers. So how would he be able to go on an adventure that actually felt fulfilling.
Just then Nior remembered something that he had long forget.
"The Ogre King's journal!" He called out.
Long ago after defeating the Ogre King and his army Nior decided to to rummaging through his castle and when he did he found the Ogre Kings personal journal. At the time most Ogre's weren't proficient in writing at all, so out of curiosity Nior brought it home to read it.
In the journal he remembered the mention of "erasing power." At the time he'd thought it was foolish and couldn't Imagine why anybody would desire to do that so he tossed the journal aside.
Frantically Nior began looking through his piles and piles of books and clutter. It took a while but eventually after hours of searching Nior found the Ogre Kings. It was bent, folded, and ripped in all sorts of places but using magic Nior fixed it up to be read.
He quickly skimmed through the book until he found the section on erasing power. In this section was mentioned a single name who was capable of such a thing. Their name was Littis and they apparently lived in smokesworth city. Without hesitation I closed the book shut and teleported over there.
It didn't take Nior very long to sense her magic aura and before he knew it he was sitting right in front of her. To his surprise she looked quite young but since the Ogre King knew her she had to be much much older.
"So what'd you want?" She questioned.
"I want you to take my powers from me." Nior said
"Take them? Why would you want that?"
"Well you see…" Nior explained to her the full story and she gave me slight nods throughout.
"I see" she said.
"Well in that case why not, but some conditions must be met for me to take your powers from you. you're gonna have to fulfill them alright?"
"Alight."
"Well first step is a vial of your— "Done."
"Already!?" She exclaimed before clearing her throat.
"V-very well, next I'll need—
This continued on until Nior had brought every ingredient. Once I did she placed all of it into a pot and clapped once.
After she did this she reached into the pot, pulling out a seed.
"Here," she said.
"What's this?" Nior asked.
"This is what you asked for, Upon eating this seed all of your power will vanish…"
