Synodian or demisiderealian is a non-binary gender alignment from the galactian system. It is partially xenic (spacialian), lunarian (selenian/artemian), solarian (helian/phoebian), and stellarian. The other part of their gender can be anything. It can be considered the demigender version of siderealian. A synodian individual can be fluid between alignments or they can experience all at the same time.
