OK, this long weekend, I am definately going to sit down and read this entire thread, it's galling me that I don't know what's been said already.
I just find it odd that Marsh never mentions where he taps gold from, and we know that ALL inquisitors have this ability, so do they all have gold spikes for no reason other than to store health in? And wouldn't they realize the ability it gives them?
Secondly, if Atium isn't really part of the wheel, is there another feruchemical and hemalurgic metal to replace it? How would hemalurgists get the powers of gold and electrum without atium, and could feruchemists still store ages, or would the next metal give a different attribute.
Also, in one of Brandon's posts, he says something about "the three worlds," I'm guessing Opelon and Scadriel are two, and the third is the warbreaker world? With all the interest in this last topic, I'm sure it has already been discussed.
Sorry I'm turning into a lurker, I'm really busy! I'll be on more this weekend!
