How to get from Exodar to Stormwind (low level), WoW TBC
If you are entering the Vault of Lights from the Seat of the Naaru (center), go left at the stairs and you will find two portals: one to Darnassus and the other to Hellfire Peninsula. If you want to get to Stormwind, take the Hellfire Peninsula portal and then click on the Stormwind portal when you get there.
