Denying fate i dont think so

[Future Esthar]

No, you're quite right. It's only Future Esthar who believes Ultimecia was possessed. Don't ask why.

Ultimecia doesn´t possess anyone.
It can´t be prooved she does and there is no machine on her time.

However I saw the machine somewhere else.
How do I know it´s the machine?

1-I saw the big version(less advanced) version of the machine and I know it´s a wave transmiting machine.
2-The telepathic properties of the advanced version will become evident when you find it.
