Anyway, if TC is the WotWE (as it stands to reason that he is... the Earth is built on the Worm's back, but the Arch of Time is built on Wild Magic, which is graven in every rock, and TC is the White Gold, Linden's seeing the Worm awaken and recognizing (and being recognized by) it, etc), then Infelice's statement that Linden has roused the Worm is extremely accurate.
Anyway, my point is... we don't know that the Land will be saved; at least, not in its current form. But what I haven't seen considered is that the Land might end much sooner than any of us are expecting. What if the destruction of the Land occurs in AATE?
The thing that really started my thinking about this was actually a quote in Runes, when Linden is being translated to the Land. In fact, Foul states that the destruction of the Earth is only his immediate goal, and that he has "deeper purposes," which he has not yet unveiled.
Could it be that Foul will be let loose from his prison to attack the Creator directly, perhaps with that conflict taking place in our own "real" world?
While stylistically and thematically I have a hard time imagining that taking place, it's intriguing enough that I have to wonder


Of course, that would leave unresolved the Sandgorgons, the Giants, and Joan, so probably not...
