So it appears that you can’t get to Exodar as Horde. You can’t take a boat from anywhere to get to your objective. No portal will help you. So blizzard, what gives? I need to switch to alliance to finish this quest? Not happening…so disappointed that I spent this time to do this and can’t finish the last step. So sad…
Talk to Zidormi to make it accessible if Darnassus is on fiya.
Mhm, just take the boat/portal from rut’theran village or whatever attached to darnassus.
Don’t worry, you can still get it! I just did this a month or two ago. As everyone above says, you’ve gotta find Zidormi (she’s in Darkshore, not Darnassus to avoid any confusion. Look for the like speech bubble on your map. If memory serves, she’s in the like northwesterly area by the coast) and timewalk back, then you can get to Darnassus and ride the boat to Exodar.
Good luck, the mount is one of my all time faves. So totally worth it in the end imo.
