Well.... Hm...
There are some combinations that myself and my roomie have tried. We both figured out what we needed when this came about, and we changed to each others titles. He needed to go to lufaise, I needed to go to pashhow. So, we got our titles, everything else, and headed out.
From what we have seen, the partner has no bearing over the first part of whatever it is we are doing. We got nothing but a single crystal each. Both my room mate and I had purple as our color. My trade was actually done on lightningsday. Still, nothing. In addition, I had charged up with my element...
After that, we tried trading the crystals to the runes themselves, tried trading to Emila, etc. No combination seemed to have any effect. After all this time, the rune will still not do anything new for me (nor will other runes), and the fortune teller herself gives me the same speech about how I seem to have forgotten my fortune.
So... after all that, I think that there is something that should be considered a next step. As I mentioned earlier in the thread, it is obviously not a time changed event, or something would have happened by now. That means the next step is forced by the user, or users.
Since we figured out the direction, at least, and part of the elemental meaning... I would think the next step does have to do with the perfect partner, since it seemed to have no bearing thus far.
So... what can we do with a partner? Who knows... trade the crystal? Well, I don't think that makes much sense... plus we would still not know what to do with them. What is it we can do together? I just don't know.... I have been trying to figure it out.
I do wish, however, that I had tried crafting with my crystal on the luck rune when I got it. I doubt that's it, but it would have eliminated that possibility from my mind.
I also wonder if the duty of the luck rune is over. We passed that part... if there is an npc somewhere... or... an item... something we have to do. That's the part that drives me crazy, there are soooo many possibilities. The luck rune did what it was supposed to do, I would imagine, and now says there is nothing out of the ordinary. Despite my best efforts, I am unable to "reset" the thing... so I have no clue.
The quotes... are interesting. The fact that they are always tied to the same element should be a hint, that is why I wondered about the tie between the protocrystals and the quote. But you are right in that there are no light and dark ones. Maybe that is a clue in itself. Since there are no light and dark protocrystals, maybe we should move off that path, but search in the same vein?
It just seems strange that SE would put in this quest that ends there. I really doubt that is all there is to it... but the next step is something abstract, something you really have to think about...
Still searching.
