Avery - chosen after her creation by a random anon. I liked the name and stuck with it
Cassiopeia - originally nicknamed 'space goth', I figured I'd take the name of a constellation for her.
Sally-Mae - chosen because you could read it as a cutesy southern name for 'Salmael'
Cassandra - a riff on Cassiopeia being named Cass. Help reinforce the idea of a doppelganger.
Argus - name taken from one of the crewmembers of the Argos
Liz - I forget. Just suits her.
