Morrowind:Map of Red Mountain

It should be noted that this map is highly innacurate, and includes all of Vvardenfell, not just the Red Mountain region, about which there is very little information shown. It actually resembles more closely this old map leaked prior to the release of Morrowind than what you will see in the game.

Citadel Vemynal: northwest

Citadel Tureynulal: northeast

Citadel Dagoth: center

Citadel Endusal: southwest

Citadel Odrosal: southeast

Ghostgate: south
