I have just finished "runes..." and had the thought that SRD may be playing with time a little more than is obvious. It occured to me that some of the characters may be reprises and perversions of previous characters.
The first thing to suggest this to me was Anele; more to the point Anele's name (read backwards). He was brought back from the dead in Andelain... might he have some connection to the shade of Elena? Could this also provide a clue to the fiery entity that surfaces occasionally? Could that be Kevin? An echo of Desecration?
Just throwing ideas around, y'know

I further explored this idea with other characters. The Mahdoubt... could this be Mhoram in some form?
We have already seen the bane of the illearth stone brought forward, could Kevin's Dirt be some kind of echo of the Sunbane, or Kevin's original desecration?
Maybe all the important events, characters, powers and banes are being brought to a single place and time in the land. We have seen Covenant, Linden,Lord Foul, Ravers, Haruchai, Ranyhyn, Urviles, Waynhim, The Illearth Stone, The Staff of Law, White Gold, Revelstone, merewives, Elohim and Demondim all being brought together. Soon the entire compass of the history of the land will be represented in one place at one time. How far behind are the giants?
Eh, just throwing a crackpot theory out there. Time (or rather the next book) may tell.
