So I was reading through the wiki looking for confirmed cases of various world hoppers and I stumbled upon a segment that explained who the three strangers were in the Purelake in WoK. I had assumed they were world hoppers but I was not aware that it is believed that one of the Demoux from Mistborn and one of them is Galladon from Elantris. This has me a little confused. While unexpected, there is plenty of room after the completion of their stories for them to become world hoppers. However; most chronologies that I have seen place Elantris and Mistborn further apart in time than what could be expected from an average life span with even more time until the events of stormlight. Do all of these stories occur almost at once or is there something about world hopping that effects this?
