If you've not noticed, [@Mifuyne], Fallen is very much fond of Zabrak.

By non-human we mean species that aren't in the near-human category on the wiki.

Sole restriction we have is that the species has to be able to speak galactic basic. Echo has the restriction on no Miraluka.

Near-human is also fine, but its interesting to see new species played out, provided they make sense.

Do try to avoid those species without any significant sources. (one-shot species, for example, appearing only in one or two books/comics)
