Vvardenfell

The island of Vvardenfell is one of six imperial districts of the Morrowind province. Its largest city as of 3E 427 was Vivec, named after the man-god Vivec who dwelt there. It is made up of eight cantons, each large pyramidal buildings, except for the Temple Canton, where the High Fane, the Ministry of Truth, and the Palace of Vivec lie.

Vvardenfell is bigger than Cyrodiil, whatever the maps say!
