Okay so while leveling your job to 50 you may have noticed that someone involved with the related quest-line has a distinct weapon, and that once you get to 50 you can get that weapon for your self. However once you do the relic quests some of them ae implied to be one of a kind. For now I know of two weapons (due to having earned them), Thryus and the Stardust Rod
  • For Thyrus, we know that it's original wielder, A-Towa-Cant, kicked the bucket at the O'Ghomara mines, however the level 50 WHM quest has him reappear to aid in the purification of the tree. However in this case it has been stated that he is a ghost essentially and fades as soon as the tree is cleansed. If his body appears as an aethereal temporary construct, why not his staff?
  • In contrast, the Stardust Rod has been mass produced. So it's wouldn't be surprising for Ququrika to have a genuine Stardust Rod as opposed to a replica or aethereal construct
Now that still leaves the other 7 (soon to be 8) relics. Are the relics truly one of a kind? Are the weapons you see their wielders use the genuine articles, replicas or counterfeits and if they are real, how did they get these weapons?
