The Aetherians are a race of humanoids from another universe, they are currently at war with the Borg Kingdom
Biology[]
The Aetherians have a fairly simple by humanoid standards, two eyes, two legs, two arms with three digits on each hand, they're taller than the average Human, being more similar in size to the Iconians than any UFP Member races.
The only non-appearance based thing we know of their biology is that for an unknown reason, they are unable to exist within Fluidic Space (home of the Undine).
Culture and Society[]
The Aetherians command a pangalactic government, known as the Aetherian Consortium, having a mantra of peace and unity, until the Borg attacked, though they successfully repelled the Borg Kingdom from their universe, many species were wiped out in the process, and so they continue the war against the Borg across the multiverse, making alliances with those who stand against them in universes such as the Prime Universe, where in 2411, after an attack by the Borg Kingdom coming from the Mirror Universe, the Aetherians made contact with the United Federation of Planets and the Alliance at Deep Space Nine.
