I just recently joined this site, so I apologize if there are already threads covering this.
What do we know/what can we infer about the powers of the Heralds? Honor sent them to lead and prepare the people of Roshar, and they carried blades apparently more powerful than regular shard blades. It doesn't seem like they had a plate equivalent from the WoK prologue, though that's not really definitive.
Surgebinding is a possibility, but Darkness (if he is a Herald in disguise) makes that far from a sure thing. And if they do, would they each get only one surge? The KR orders share from 2 different Heralds orders, so that would seem odd if their own followers had more diverse surgebinding powers than the Heralds themselves.
Obviously they have some form of immortality, but we don't get much info on what thst might grant them.
Thoughts?
