If I was allowed to join, I'd love to do a race that lives on an island that's been mostly avoided by civilsed worlds because of the lack of policing there, where mobs rule the streets, violence is a day-to-day occurance. Kind of like tattoine (with the hutts ruling almost everything), except a lot more violent, and mosst of the people there turning out to be theives, admittedly their engineering skills aren't that great, however their world, being mostly untouched by other races (as it's considered an unfit place to be, so no one even mines the resources), has given them the opportunity to develop rockets and the like. Admittedly, there will be the occasional mishap where something blows up, killing a few, but those who have made it up into the skies, usually become pirates of sorts, either that, or traders in a black market. The few who have made very sucsessful ships that can travel to other planets faster, or navigate easier have been known to intergrate to other planets, while generally being abused from day-to-day, live by helping construct, or further said planets travel potential (i.e. helping to make better rockets etc).
Their appearence would be a mixture between a rock elemental
, their back, arms, the back of their head and their feet being the tough skin (where it is slightly rougher, like the rock elemental), but in general being smaller and nimbler, if that makes any sense.
Reproduction; Most, if not all of the species would have sex organs like humans, that can either fold away, or becovered by a fold in their skin. As they aren't usually family-loving creatures (i.e. they are social, somewhat, but tend to veer away from staying as partners) at specific times of the year, like certain animals on Earth, have a specific place for mating, and mate as one big group (that is, essentially, a swingers party, where lots of people are mating at the same place, but paired off into small groups/couples).
Their solar system is quite small, and all the planets are quite close to the sun, making their skin likely to be darker,, and have less, if any hair.
Hmm, I can't think of anything else there needs to be discussed about it...
