Oh boy I can't wait to see How Xehanort gets her into his little gang
But seriously, given that they only used "Seeker: in one other context (well "The Gathering" aside), and that the writers and staff seem to be very detail-oriented, I question why the choice of title.
I wonder, if she has anything to do with the words that popped up all the ay back to vanilla KH2's secret ending?
Also I can see either Invi or Gula getting some variation of "Spy"
Pfft, lol, considering Nomura's penchant for "surprises" and extra twists that could even be a viable possibility somehow.
The official Twitter message coming with the picture does speak about her task of "preparing strong Keyblade Wielders for the incoming Darkness" and in order to do just that she has to
seek out strong hearts beforehand so in this vein it would fit somewhat outside the "Seeker of Darkness"-meaning.
The words in vanilla KH2's secret ending were "Chasers" though if I recall correctly, not Seekers.
Possible, although of course things like Mediator or Observer are also possible for Invi while Gula could also get Investigator.
Hrm the seeker title (at least I called someone having even if I called the wrong person) is interesting because of the implications. On one hand there is the obvious ones like her seeking out dandelions. But you could view it in another way, of all the foretellers Ava was the only one who to the bitter end was seeking a way to change their fate. Hunting down the traitor was not her job, heck she wanted to believe there was no traitor, but she kept seeking anyway. Eventually seeking out Luxu where in she attacked him believing that he was the traitor and she could end all of this right now if she took him out. It was sad, it was desperate, and all Ava ultimately wanted was the truth but once she got the truth that hopeful girl we know had been the one most against the war went on to fight anyway. When we next talk to her she sounds broken, defeated, and her only words of advice is that some truth shouldn't be known. So when you consider her seeking for answers and how her story ultimately result in her finding a truth she refuses to face/accept, the title of seeker does actually fit her quite well. It would certainly be interesting though if Ava ended up a seeker of darkness just because she is the last person you could see that.
You know part of me hopes that Ava found a way to save her friends. While the MoM seemed to imply they won't live in reality we know he can only write what that keyblade saw. Ava was able to send the Dandelions away to place of protection the other foretellers can't reach, so maybe just maybe she found a way to send her fellow foretellers to a place of protection to. I always liked to imagine this what-if scenario where the 5 foretellers clash and Ava in a final moment of desperation to stop her friends from destroying one another does the only thing she can, she raises her keyblade and with a scream she locks each of them away in another world outside all this like the dandelions. But the battle was too much for her and that last bit she did took all the energy she had left. Ava collapses and dies fading into light to leave not a trace. Without Ava her friends are never released and so with her last breath while she saved them she also imprisoned them. But in this way she's has preserved hope for if one day someone can free them then they can go on living, in a time where the war and fear of the end that fueled their conflict is long past.
Of course that's totally baseless but it's a nicer thought than assuming the foretellers all murdered one another in cold blood, never resolving their problems, never repairing their friendship, and never finding out the truth behind everything.
I think in DDD Yen Sid also spoke of the "Seeker's life" in general so it may be a given that it can have a multitude of meanings with not all of them connected to the Seekers "of Darkness".
If one wants to put it in even more general terms, the entire KH series is somewhat full of "seekers" in one form or another.
In KH 1, Sora is a seeker in the form of looking everywhere for Riku and Kairi, a task which carries on into KH 2 while stopping a bunch of villains on the way.
Donald and Goofy also fit as they search for their King, they're also seeking something.
In CoM, all three of them seek the truth about memories and the mysterious Naminé.
In BBS, TAV are also all seekers, with Terra seeking a way to control his Darkness, get his Master's/father figures approval, attain his dream of becoming a Keyblade Master and last but not least find the strength to protect those he holds dear the most (Aqua and Ven).
Ventus is searching for answers regarding both Terra and his own nebulous past as well as to get a broader and more refined view on how friendships works while Aqua is seeking for a way to balance out her feelings of attachment and friendship for Ven and Terra with her duties and obligations of her new Master title as well as to protect "her boys" from Xehanort's machinations.
Roxas' entire life basically revolves around seeking and finding answers as does Xion's and to a certain degree even Axel/Lea.
As on the "Ava is a seeker of darkness"-bit honestly I can see her and possibly more if not even all the Foretellers like that, mainly due to Nomura's knack for mucking the storyline up for the sheer sake of surprises. In that vein, I wouldn't be surprised either if the 13th turned out to be either Skuld or Ephemer somehow.
Heh, interesting theory, although on that last part about never finding out the truth behind everything I dare assume that this is intentional as finding out the whole truth behind it all is probably one of the "wham"-points of KH III itself.
