Talenel'Elin, Stonisrew

Thanks for all the feedback, and I can see why these are unlikely (maybe not the Regrowth one idk) because I have not actually read all the books in the cosmere, just Mistborn 1-4 and Stormlight, so I much about the time around Elantris

These may be already on here, and I'm sorry if they are. I have two theories on Hoid, but I have no real proof to back them up, just speculation. We know that Hoid can travel forward in time, but not back. I think this could be because he is using a Speedbubble, either for a,long time, or a very strong one. We also know that Hoid can regenerate very quickly, since he told Jasnah her shardblade would hardly hurt him. I think this may be because he can compound, using gold like Miles in Alloy of Law. Do you guys think these could be right, or are they already disproved?
