Sounds good. Although I have proof Hoid is NOT a Shardholder, and i think therefore we need to admit the possibility that the letter was not necessarrily written to other Shards of Adonalsium, but maybe to other immortal world travelers, who have both those powers some other way.
Interview with Brandon:
1. Are Kaladin's parents still alive, and if so, are they actually mad at him?
2. Is Hoid a Herald, or a Shareholder, or something else entirely.
3. Was the letter posted on the top of chapters to Sazed?
4. Do dead parshmen turn into Chasmfieds?
5. What is the dark-glowing sphere?
6. What did Szeth do to become a Truthless, and is there anything else involved in being a Truthless that we haven't seen?"
1. Yes, they are still alive. RAFO.
2. Hoid is something else entirely.
3. It is written to a character who exists outside of Roshar. I won't yet say who.
4. No.
5. Major big RAFO.
6. Szeth was perceived as betraying his people in a fundamental way, and you will learn more about that when his book comes along
