This solar sail ship is what Mylar uses in her pilgrimage through the universe.
Travelling through the aether is rare in Mylar’s time since the creation of a universal gateway system between all the planets, few of these ships are still being used
Other ways of travelling the aether include the use of solar whales like a blimp
Unlike space the Aether has breathable air. The planets are much closer together making Aether travel take a reasonable time. The planets are placed in order by universal magic and float through the aether on a slow wave.
