As I promised, here is the Azulians' description sheet. I finished it yesterday, but was too sleepy to write their info.

When Azulians first arrived in Polis Prima, Earthling scientists were astounded by the visible similarities between their anatomy and humans'; however, further experimentation proved that Azulians are beyond the mere concept of physical appearance, and they adopt whichever they see more fit in each occasion. They also adjust their behavior to best fraternize with other species.

Azulians soon proved to be able to breed with humans, although their adaptation produced a curious side effect: they have three genders. A human can have sex normally with an Azulian of the opposite gender, but to successfully produce an offspring, all three genders must take part in the process; the third one, called adaptator, must merge with the male subject before the act, which will adjust his DNA and make it compatible with the female receptor.

Azulians are one of the few alien races known to have a religion. They believe in Zoon, a superior being who created them to bring joy and peace to the whole universe; it is said that Zoon itself isn't a being, but a sort of hereditary title: every Zoon is child of a previous Zoon. Zoonism is currently Polis Prima's majority religion, and owns an area in the city's Ecumenical Church, where rites are celebrated periodically.

Azulians do have human nipples and genitalia, but I omitted them because everyone in FA are serious artists and don't really like penises.
