Yeah, you have a point. Thanks for your notings. Updated. Now he's 635 years old, assuming that the timeline is in the 21st century, so he should be at least be from the late-Middle age. And now I would have to find a way to make the lore sound logical. Again, thanks for reminding me of that

Edit: So he wandered in the old palace ground for hundreds of years until the offer. That sounded a bit awkward, but I wanted him to be revived just right after his death, because of the anger for those irresponsible guards, and there's no reason to revive him just to put him back in society as a scary skeleton. So please bear with me that.
