explain the gate where all the warrens open onto chaos don't you remember how Quick Ben found Shadowthrone in GotM he sends his mind into chaos to find the mouth of the fragment in which Ammanas resides
As far as I understand it, all of the warrens reside withing chaos, kind of surrounded by it. Thus, they must border on chaos somewhere. And I seem to remember Quick forcing his way in. But I could be wrong.
There is also a link to each of the warrens from Starvald Demelain (sp?), although I doubt that's what was used.
@mtlhddoc2 - As far as I'm concerned, the Warrens and Holds are the same system. They aren't necessarily the same power source, but it's the same general idea, and the only real difference is that one is more evolved than the other.
As for the tiles, and the Deck of Dragons, they correspond with the individual holds/warrens. They are part of that same system, not a system unto themselves. The "earth magic" used by Samar Dev and the Wickan warlocks is indeed a separate system, I'll give you that. We don't really know what the magic used by Quick with his little figures is. It could be related to the warrens, it could be related to spirit magic. I doubt it's its own little system. Quick's a clever guy with access to 12 warrens. I'm sure he can figure some stuff like that out.
"God magic" as you call it, so far, seems to be aspected to that god's warren, and could be explained using the regular system. For instance, Shadowthrone uses shadow magic (I never can remember whether he's in Rashan or Meanas). Rake uses Kurald Galain. Osric uses Kurald Thyrllan (or is it Liosan? I also have difficulty remembering with the Leosan). I admit that I don't really understand Elder Gods' magic, but they don't really seem to be aspected. Regular old ascendants though, don't use any special type of magic. Just the warrens.
From what I can tell, most of the magic in the series is based around blood. We know that the elder gods get power from blood. We know that the warrens basically are K'rul's blood. We know that blood is utilized in spirit magics, if not it's exact purpose. *SPOILER KAZ THIS IS MARKED SO YOU DON'T READ IT ALTHOUGH IT IS REALLY QUITE MINOR AND YOU PROBABLY WON'T GET IT UNTIL YOU READ THE 7th AND 8th BOOKS ANYWAY*
The magic used by the dying god (though not the redeemer, I don't think he ever even used magic) is also related to blood, since that's really all that the Kemyk or whatever it is contains. The Dying God's Blood. [/SPOILER]
The magic of chaos is part of the magic of the warrens. If you remember, in the first book, Hairlock utilizes it too. It's accessed in the same way as a warren and allows the same general things. It's just that it can hurt you a lot more than the warrens can when you use it.
I think I covered everything in your post. It's mostly just a matter of opinion, though I (of course) think I'm right. Anyway, hope I got all of my facts right. If you notice anything that's wrong, please do point it out. If nothing else, it helps me remember better so that when the next one comes out I don't have to re-read all of them. Although that might not be so bad with these books.
EDIT: I also forgot to mention, if you get confused, a lot of times,
this page on wikipedia will clear up your questions. Though you have to be careful of spoilers, cuz there are lots. This includes comprehensive knowledge from the books (most of it anyway) and some stuff from erikson too. So yeah.
