I don't. Two reasons: first, and most importantly, I don't have the references for it (I came to start collecting SR only recently and don't have most of the 1 and 2E stuff, and don't really have a campaign to use it in), and second, I don't particularly connect the past history of Earthdawn with the future history of SR*.

*: I see how they may have been trying for it, and that's fine - it is their product - but I conceive of the two as being on alternate Earths. (No Troubador Adepts in SR!)

EDIT: So if anyone wants to explain the Immortal Elves to me in detail, feel free.
