Echo Vision Frequency

[Gemina]

I'd have to rewatch the scene to be sure, but I never got the impression that Fordola deliberately looked into our past. It's just part of her constantly-triggering visions.

This. Fordola welcomes her prison cell because it stops the visions from happening. How she is able to harness the power and keep it from driving her insane, and/or incapacitating herself in battle like the WoL is another story.
