Missing campaign quest items

[Skyseeker]

I've just logged back into an old character after who knows how long, since before the campaigns had roye in them I think... anyway, I'm trying to do the quest "Hidden fortress"(lv 59) but since I haven't actually done the previous quests which are marked as completed, I don't have the "translated document" I'm supposed to read before interacting with the traces of roye, which I can't do. Is there any way around this or to be able to get that item?? I've tried talking with Lamidros in the monitor farm but that does nothing.
