So, I actually read through those walls of text
Some interesting info
So, all of the maids who use time magic, are clones. Not a big surprise, I feel like that was already spelled out. But they're all clones of the Time Saintess. Shitty clones, of the time Saintess, but their logic is, 'if our clones only can reproduce 5% of her original power, we'll just make 20 clones'
The problem is in the fact that a clone has a unique soul, which maybe doesn't click as well with the power set granted by their body and mind. Hence, all the imperfect Time Saintess Clones.
But then you have the opposite, which is how we got the Time Dragon.
The Rainbow Saintess, Raksha (who we haven't seen a lot of I had to look her up to even put a name to a face), is another success story too.
So clearly, these people are a bit too cavalier with all of this cloning Saints business, considering its 50/50, either get a new Saint or get a demigod intent on killing you. Potentially this is the identity of the "real" traitor, someone resurrected, but with a fucked up soul, resulting in a repeat of the Time Dragon.
Also its implied that the old kingdom was super fucked up. A reason why there isn't a current developed understanding of Souls, but there is technology to recreate your Mind and Body, is because early research was in fuel efficiency of Souls. So they tried to power a candle flame with just souls. Took them one hundred souls to make a fire burn for 10 seconds. They felt that was something not worth researching. But, like, christ. Imagine losing your immortal soul to a meaningless experiment that only resulted in a candle barely burning. Gone to the void, because, hey, we figured after using 10 souls and the flame barely got going, another 90 more wouldn't hurt.
