Exodus Airships is the sixth and last panel in this mural.
The last panel in the mural series shows the exodus of airships leaving the panet, assumingly for the Stargate. It's easier to head over to an inhabitable planet on the other side than to wait for your homeworld to be passed through the Startgate. Or is it to pass the Stargate over your planet?
