Here's a list of some of the locations that haven't been confirmed yet, but Zenimax has to put into the game, or else it will break the existing lore.

First off: The Dwemer Ruins in Morrowind.
 * 1) Andre Maul's Tower
 * 2) Arkngthand
 * 3) Arkngthunch-Sturdumz
 * 4) Bethamez
 * 5) Bthanchend
 * 6) Bthuand
 * 7) Bthungthumz
 * 8) Dagoth Ur
 * 9) Druscashti
 * 10) Endusal
 * 11) Galom Daeus
 * 12) Mudan Grotto
 * 13) Mzahnch
 * 14) Mzanchend
 * 15) Mzuleft
 * 16) Nchardahrk
 * 17) Nchardumz
 * 18) Nchuleft
 * 19) Nchuleftingth
 * 20) Nchurdamz
 * 21) Odrosal
 * 22) Sorkvild's Tower (Called something different)
 * 23) Tureynulal
 * 24) Vacant Tower (Should be called something different)
 * 25) Vemynal

The reason for the inclusion of these locations is quite simple: They don't have a choice. The Dwemer disappeared somewhere during the First Era. They still exist in the Third Era (they are in TES 3), so, logically, they must exist in the Second Era as well.
