This addon simply changes the Dazar'Alor map to the Zuldazar map. You may still view the Dazar'Alor map by clicking on it manually, but with this addon when you open your map within the borders of Dazor'Alar it should default to the Zuldazar map.
Adapted from the work of scainburger who made "No Thunder Totem Map" back in legion, who no longer maintains it and gave permission for me to upload this adaptation.
