How do you manage to get Korundi to betray you? I've been trying to figure that out forever. I thought it might have to do with blackmailing her, but that option is currently bugged, so I assume it's not that.
Early on, Korundi is outright hostile to a particular theory about what happened, if you raise it. A moderately good advisor will warn you why. If you pursue this angle obliviously, it can end very badly.
