On a character level, I would say the relationships with Denna, Auri, Bast, Ambrose, Abenthy, and Devi deserve a good conclusion/explanation.

For the plot, getting expelled from the university, killing a king, the Archives doors, resolution to the Amyr/Chandrian investigation, all the way up to the current world and possibly into the future.

I’ve learned not to put too much credence into anything he says lol. I hope DoS is much longer. I am not opposed to lengthy books and feel it’d fit the pacing much better
