Darkovia is also mentioned to be part of the stage ArchKnight (DF) plays in on several occasions.
Verata: Soon my minions will branch out taking over all of Darkovia!
Oaklore Keep is mentioned to be near the place where Adder hails from in AQ.
Adder: It isn't just that simple, friends. When I was little, I lived near legendary Oaklore Keep far to the west. But then my life is a blank. Next I remember, I am here, in Isle d'Oriens.
Falconreach is mentioned to be sacked by the forces of Visia and the Mutant King in AQ.
Kragoth: I DON'T THINK SO, witch. You've already shaped me. Remember Falconreach? Do you recall Felini, Cysero's apprentice?
Kragoth: I was an awkward, spindly, kindhearted 19-year-old mage. You turned me into a warrior with a lust for destruction, and the strength of ten men.
Kragoth: And THEN, once Falconreach was destroyed, along came your accomplice... the Mutant King. HE turned me into a monster.
Amityvale is mentioned in the Hall of Memories.
Drageth Slugwrath: No, I agree.... but my men have searched from Amityvale to Luminovia to no avail, my dear. He is quite simply... gone.
Krovesport is mentioned by Ketra in Hunter's Paradise (DF).
