We have enough topics about the bad or confusing ESO lore.

Here is one dedicated to the stuff that really adds to the story of Tamriel.

Let me begin.

Both books are quite interesting. The first tries to emulate Kirkbridean metaphysics, it seems, and it doesn't fail as badly as I was afraid it would. The concept is rather interesting, to be honest. Thoughts on the matter? Maybe Falinesti stopped walking in the 4th Era because... you know... the story hasn't found its ending yet.

The second one fleshes out the Ayleids and their belief system. Now we know how the old Elven pantheon and the Daedra worship the later Imperials accused the Ayleids of fit together.

Although I thought the Ayleids did not actually worship the Daedra, but more being in some kind of cosmic business relationship with them. that schism storyline works rather nice, too.

I like that second one. Not only does it give us some background on something we've speculated about for a long time (Ayleid migration into Valenwood), but it also brings up Ayleid Daedra worship, which is something that has confused me a bit in the past.

I've seen the first one before, though, and while it's pretty, I wasn't really impressed by it. It's effectively "Kagrenac in Valenwood," with some background details changed around. I appreciate the effort, but the story is just too similar. I hope, if there's a questline attached to this story, that it proves to be more... if I say "original," I'll probably sound too mean, but that's really the only word that fits, I think.

There is a questline to deal with the machine that leaves many unanswered questions. One is what happens if kinmune enters that machine?
