For most people who have only watched the movie, but not read the book, you might be unaware of the existence of the Blue Wizards, who were Istari, just like Gandalf, sent to Middle Earth, but went to the East of Middle Earth.
Well, I felt that with the Major Quests said to be planned, I was thinking of a Major Side Quest involving these Blue Wizards. I felt that the Major Quests, if it were following the story of the book, might miss out the Land of the Easterlings and Harad (unless Mevans somehow blows us away again), while I havent thought of anything for Harad), I think these Blue Wizards and their quests could be a feature to bring questing to Rhun.
While lorewise, not much has been said about these Blue Wizards, I assume that they were also helping to prevent Sauron's rise, in Rhun somehow, and I am also unsure of how these Major Quests are planned to be implemented, whether it is like Mevan's other mod, the Lion King mod, or some other way entirely, I think the Blue Wizards could be implemented the same way as Gandalf and the other Quests, with rewards like Blue Wizard Robes, or their Staff, and the quests could be sabotaging Easterlings or killing some of them, kind of depends on what the Major Quests will be like.
So, what do you think? Should the Blue Wizards be added? If they should, should they give quests? Is this lore-friendly (it might not be, I havent read the book in a loooong time, this is from my memory)? Leave your thoughts below (critism welcome)! :)
