You might be seeing Telvannis it belongs to the Mage Lords of House Telvanni and is just of the north east of Morrowind or it could be Sheogorad. Akavir is very (very) far east of Tamriel you might be seeing Atmora but thats more north west of Solstheim.

There is a unofficial map here it seems pretty accurate though.
