Guild Wars 2

This is a general question from me to any/all of my fellow players, not groping for dev responses.

When completing "Through the Looking Glass" the other night, I saw that Tegwen and Carys were coming along to help us fight the Eye. I thought, "Oh, nice, I remember working with them after losing my mentor at Claw Island."

Yes, as a Priory member, after Claw Island I had previously elected to head out and find two sylvari who might help us out -- Tegwen and Carys -- in the mission "Shards of Orr".

But here in this Pact mission they are introduced to me by Trahearne as if we had never met, and their dialogue never calls back to our earlier meetings.

Interestingly, the hylek that appeared, as that was the race I chose to explore on this character, did remember our time together in their dialogue.

So this got me thinking:
What across our whole personal story actually carries through, and what was merely an illusion of personalization?

Some of this I think we all already know -- the selections you made at character creation affect which story paths you take in the first few levels, but once you head to Lion’s Arch to meet up with your order that is all completely forgotten. Just like what you do with your Order ends up being forgotten once it becomes all about the Pact.

But I might be missing little details! I would love to know if anyone has compiled a list, or started to collect information for one, about what meetings with NPCs and choices made when selecting between mission paths and so forth actually gets reflected in later missions or dialogue. I am hoping there is more that I have missed, but so far I am a bit disappointed in how little earlier portions of story effect later ones.

If there isn’t such a place, is the official wiki an appropriate setting to make such a page? Would there be any interest in laying this all out [though it likely would be spoiler-heavy]?
