Grandpa
Charles Best was having a spectacularly bad day, which fit perfectly with the horrendous week that he just went through. For reasons he could not completely comprehend, he had reincarnated.
His original identity was that of shaman king from the Dark Elf race, but that was merely the most mundane identity he carried in his previous life. He was a third generation elf, meaning he was only two generations down from the birth of the very first Dark Elf in this realm ever!
As such, when he was born, the Origin realm had only been stable for a little over 10,000 years, with its actual age being near 100 million years, as compared to now when it was already nearing 14 billion years!
