I have this ongoing concept of a planet with two evolved races inhabiting it, both evolving for a very distant ancestor which wasn't unlike an Earth sea-slug.

The two forms of life were the Fermax (a tall, purple, matriarchal race. Think a giraffe meets purple sea-horse with teeth) and the Limoux (smaller, green with branching orange exterior lungs, genderless and more nurturing. Think sea slug meets a rabbit).

So here is what I'd think an earth issued passport would look like. The logo for the Limoux on the left and the Fermax on the right.

Just a bit of fun. ;>

I really should concept them more.
