Retcon

Trivia: Retcon is also short for "Retroactive Continuity", a term used when creators actually change something that happened in the past of the work into a new continuity. In this case, the DDO devs were pointing that the Devil Invasion event (that at the time took place after The Shroud, as vengeance) actually happened years before you arrived in Korthos.

As soon as you arrive at the excavation site, if inquired, it will only reply:


 * Retcon: Miss Nelle Gann is in charge here - you should speak with her.

After you talk to Nelle Gann and she welcome you as guests, if you talk to it again, it will say:


 * Retcon: Miss Nelle is too trusting - I shall watch you, as I watch Tremas and his men.
