hi. I'm new here.
This is the only place I could find anything on the Hoid phenomenon that I noticed after reading Mistborn and Elantris, and even though I'm not sure of what half the stuff you guys are talking about is, I'm really interested in this Shardworld stuff.
(I can tell by your writing styles that you're all considerably older than I am, so bear with me if I'm not throwing analytical points around) I figure I'll throw my two bits into this discussion:
I noticed that somewhere you were trying to figure out what the six shards are, and I found Q&A where Sanderson gives the answer to that:
-Ruin, Preservation, Adonalsium, Hoid, BioChroma, and the Dor.
As for the ideas about Hoid being SlowSwift in HoA and the Terris steward in WoA, I think they're both unquestionably true.
Finally, about Hoid's statements on where he learned his storytelling(I just finished Warbreaker) I don't see why those can't apply to Mistborn or Warbreaker itself. Gods die in both and as for the lands coming together, I don't think we know enough history of either world to make a judgement call on it. Could be Hallandren and Vivenna's homeland for all we know. (Hoid was in the future?)
