I was wondering if you could elaborate on a past wob. You said that Hoid and Frost are two of the oldest beings in the Cosmere. Does that include the vessels? Are the original 16 vessels younger than Hoid and Frost?
Brandon Sanderson
In the current outline, Hoid predates the others by a bit--he'd already started aging oddly before the Shattering. But that's not strict cannon yet. (You can find evidence of it in Dragonsteel.)

Questioner
Probably a question you are not going to want to answer but how old is Hoid?
Brandon Sanderson
How old is Hoid? ...Hoid is older than the Shattering of Adonalsium. Hey there is an answer for you! He is very old.

Questioner
Is Hoid a dragon?
Brandon Sanderson
Oh I will give you a RAFO card. You're very good, Have you read Dragonsteel?
Questioner
I have not but--
Brandon Sanderson
Don't read it, it's bad.
Questioner
Okay then. I am just-- What? Okay then. That's awesome. We have some ideas but-- Hoid is amazing. I figured he was really old but it's cool knowing for sure that he's exceptionally old.
Brandon Sanderson
He is one of the oldest people in the cosmere, but he is not the oldest.
Questioner
Ahhh...
Brandon Sanderson
The person he is writing a letter to is indeed older than he is.

How old is Hoid? Or better yet (to avoid any trickiness), how many years has he lived through?
Brandon Sanderson
He's been alive since Dragonsteel. However, he may not have spent all of that time awake and alert.
