The Exodar is a dimensional ship that was used by Velen and the draenei to escape Draenor and arrive in Azeroth. It now acts as the draenei capital city in Kalimdor on Azuremyst Isle.  

During the Burning Legion's third invasion of Azeroth, the Burning Legion led by Rakeesh attacked the Exodar in order to destroy the naaru O'ros in order to keep the secrets of Light's Heart contained. Rakeesh was killed by the adventurer and their respective order hall champions, and Velen realized Rakeesh had been his son, and that he had foreseen this day. After the battle he ordered Grand Artificier Romuul to begin repairs on the Exodar, stating that they were going home.
