Mourn's Vault

Mourn's Vault is a settlement in Sadeas's princedom of Alethkar. It's on the border of Alethkar and Herdaz, northwest of Hearthstone, and relatively close to where Lirin, Hesina, and baby Oroden currently reside.
Further, Mourn's Vault also seems like it could be in the general area where the interlude with Sheler takes place ... which is a thing that is easily missed: Tien was in Sheler's company when he died.
Also, a member of every order of Knights Radiant was present there (assuming Ash will be a Dustbringer) at the moment when Dalinar united the realms, as well as every flashback character.
Additionally, Tarah moved to Mourn's Vault from Amaram's princedom to work as a scribe. Still, Mourn's Vault is not a pleasant area of Alethkar.
