I've been wondering about this for some time, and I'd really like to hear other people's thoughts. The thing is, I don't want to spoil, and some of my questions touch on stuff I read in the Gradual Interview, things that perhaps might hint at what's coming in Fatal Revenant. So I'm going to err on the side of caution and spoiler cut like mad.
So, in WGW, Caer-Caveral breaks the Law of Life. This enables Covenant to give Lord Foul one square in the eye, despite being dead, and all ends well.
As of Runes, what exactly does being dead entail? Has it changed?
As of WGW the Dead are held apart from their deserved rest by the breaking of the Law of Death. They're incorporeal. They seem to be omniscient, or nearly (They can see the future; Hollian had "spent time among the Dead and seemed certain of her knowledge.") (Except Kevin seemed as fundamentally clueless as ever he was in life, but okay).
After Caer-Caveral breaks the Law of Life, only Hollian and Sunder return to corporeal, breathing existence -- I assume because their restoration was the means of breaking the Law, not the result of it. Covenant, at WGW's end, isn't corporeal -- he's "not physically alive." He's able to absorb Foul's malice and defend the AOT, but he's still a shade, am I right? His abilty to affect reality seems limited to the non-physical plane.
So, what I'm wondering is...
Ware -- Gradual Interview references --Speculation and Fatal Revenant mentions
Spoiler
Let's say that Covenant is the Fatal Revenant. Will he be corporeal, or at least able to affect something on the physical plane? Has his long stint upholding the AOT affected him? How about all the Foulness he absorbed -- is there any basis to the speculation that Foul and Covenant have become, or are becoming, one?
Are the Dead, in fact, now capable of change?

Perhaps this was an effect of Andelain and/or the power Caer-Caveral used to defend it? Did Andelain act as a time caspule? I only ask this because Sunder and Hollian said they were "sustained, and in some measure defined, by the soveriegn Earthpower of the Andelainian Hills." They couldn't leave it without physically dying again -- and everything within Andelain seemed to exist in a sort of suspension, timeless and apart.
I don't really buy that. Just an idea. But whatever the reason
Spoiler
ETA: I forgot to ask one other question: Is Covenant likely to be omniscient, like the Dead of WGW? How could that possibly work, structurally? It seems to me the Dead of FR, specifically Covenant, will have to be significantly changed from previous Dead for this to fly. But how can that be?
