We know who it is. Bernkastel - name keeps coming up. Working with that ghost claiming he was an emperor. You know, all the stuff you mentioned on the Network before.

[For a guy who supposedly got stripped of most of his emotions, Geralt sounds pretty irritated.]

The question is what she is. She's clearly some sort of malicious ghost. Has a lot of magical power to be doing the things she's doing. We need to find the source of her power and we need to stop it. I'd bet my whole purse she's drawing power off the ghosts she's trapped somehow, maybe like a hym feeds on remorse.
