As he stood still, watching the woman on the wall, Rey remembered the words of the Elders.
He was reminded of her sins.
'Apparently, what is known as The Oracle is an amalgamation of the wills of all the predecessors that came before the current host, all of which will be embodied in one avatar.'
The current Oracle had the joint personality of the ones before her, and if Esme became The Oracle, she would suffer the same fate.
'I can't allow that. If she goes through with it… she won't be Esme anymore.'
To stop such a thing from happening, the only visible hope he had was the Elf that was currently before him.
'I just have to find a way to untaint her. But, even that seems impossible at the moment.'
Still, it was far better than the alternative.
Elves that were born compatible with the Oracle—like Ciela and Esme—were only born every thousand years or so. There could also only be one at a time.
