I'm a recent joiner for editing this wiki, but have been following for quite some time... I added some additional support today to the "Adonalsium" page and was wondering - where did you get the spelling?
The quote I included as additional content for this page was from Sazed in Page 344 in The Hero of Ages, preface to Chapter 39 and it states:
"I sense shards of something from long ago, a fractured presence, something spanning the void. I have delved and searched, and have only been able to come up with a single name: Adonasium. Who, or what, it was, I do not yet know.
Here the spelling is Adonasium. That appears to be the correct spelling to me. Is this word spelled as Adonalsium in some other book? (I'm currently re-reading all of Sanderson's novels, and just made it through the Mistborn trilogy).
