The Thirteen Great Cities were the jewels of The Empire, strewn all across its lands they were the centre of political, economical and cultural power that the rest of the land could but follow.

Ten of the cities met their end in The Fall, with only Llewynfrid, Maras-an-Eithil and Zak Garaz surviving its events. Since then only Llewynfrid remains what it once was.
