Aster's Hope. An apt name.
The Aster. A flower, traditionally a symbol of hope, and named after "The Star Maiden" Astraea in Greek Mythology, who's tears fell to Earth and turned into star shaped flowers. One of the characteristics of the Aster is that it is resistant to drought and can grow in sparse, dry lands. (much like those featured in Odyssey's tenuously-atmospheric worlds)
It is said, that Astraea will one day return to Earth. (much like the atmospheric worlds we hope, one day, that we will return to)
