Do we know how the timing lines up on Scadrial and Roshar? In TWOK Demoux is seen worldhopping on Roshar, meaning the non-flashback events we've seen on Roshar must occur after but within decades of the Final Ascension on Scadrial. In Mistborn Secret History, Kelsier only learns of worldhopping around the time of the Catacendre. He is widely theorized to be Thaidakar, but the Ghostbloods have presumably been operating for decades on Roshar. When did Kelsier establish the Ghostbloods? Also, Demoux followed Kelsier in life, later becoming one of the founders of and most dedicated adherent to Survivalism. What are the chances that he became a worldhopper but NOT a member of the Ghostbloods?
I assume this has been discussed before, but I couldn't find anything written on it. Have I made some faulty assumptions?
Thanks!
