4 questions: 1.
2. The Letter states that, "Rayse, on the other hand, was among the most loathsome, crafty, and dangerous individuals I had ever met. He holds the most frightening and terrible of all the Shards...One need only look at the aftermath of his brief visit to Sel to see proof of what I say." Was Rayse the cause of the Reod on Sel that caused the chasm and the Incomplete Shaod? 3. Shallan is a Lightweaver, so has the surgebindings of Illumination and Transformation. Jasnah, as a Elsecaller, has Transformation and Transportation, allowing her to enter Shadesmar in the flesh. How was Shallan able to enter Shadesmar without the use of the Transportation Surge that Elsecallers and Willshapers have? Jasnah chided her for entering with only one sphere, so does that mean that anyone can enter Shadesmar, assuming they possess the requisite amount of Stormlight?
4. For Worldhoppers and Shards alike, how long does it take to travel from one world/planet to another? Is it a kind of space travel through the physical realm, or a more instantaneous travel via cognitive/spiritual realms?
