Now, I doubt there are any elves that have lived that long in the Shadow World or Middle Earth - but how could they even perceive humans as anything more than very intelligent and very short lived pets?
Actually, that could work for the Lords of Essaence (or Orhan/Charon beings as well). And even a number of elves in the Shadow World have seen two Eras (Kirin being one of them, obviously).
My personal interpretation is that most elves do not go into that - some of them do, and the rest of the world consider them insane. Most of them let the memories stack and be buried under more recent ones, choosing to live in the "now" rather than deal with the infinite. Erlini are the typical example of such a survival mind reflex.
Anyway, enough derailing this thread... I'll go back to lurking and trying to wait patiently for the release of Emer III.
I do wait as well, but mostly for collection purposes - I am currently running a fairly high-level campaign in Uj than spans the entire region (and spills over into Izar, Khum-kaan and Namar-Tol), so I had to make up a number of things - more detailed cultural description, a handful of city maps (including Kaitaine), Notes on past events, a poster-size regional map, and I started a more detailed description of Kaitaine.
I did the same for Saralis in my previous campaign, and for Urulan and Kelestia in the one before. Typical story of most Shadow World GMs, I guess :p Of course, I did Saralis before Xa-ar was out, so my version is not in line with the official one. I guess my version of Uj will not be in line with Emer III either
