A race that lives on a planet that's been mostly avoided by civilised worlds because of the lack of policing, essentially where mobs rule the streets, and violence is a day-to-day occurrence. The whole planet is like tattoine with one group (the hutts in Star Wars) ruling almost everything. The only thing that's different is the whole planet is a lot more violent, and most of the people who go to stay there / crash there or are born there turn into thieves. 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, thus no one even mines the resources), has given them the opportunity to develop rockets and other sources of transportation, some of which may not be available on earth. Of course there will be the occasional mishap where something blows up, killing a few, but those who have made it up into the skies, and stay there, usually become pirates of sorts; attacking, pillaging, and looting other ships. If the ones in the sky don't become pirates however  they will usually embark in trading in a black market. It has been known, however, is rare that the few who have made very successful ships that can travel to other planets faster, or navigate easier have been known to intergrate to other planets, aside generally being abused from day-to-day (from the planets that know what species s/he/they is/are), live by helping construct, or further said planets travel potential (i.e. helping to make better rockets etc).<br/><br/>Their appearance would be a mixture between a rock elemental (http://wiimedia.ign.com/wii/image/article/782/782515/godzilla-unleashed-20070420051910820.jpg) and gollum (http://foreverloyal.files.wordpress.com/2008/01/gollum.jpg), 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.<br/><br/>For reproduction all of the species (excluding anomalies such as mutations) would have sex organs like humans, that can either fold away, or be covered by a fold in their skin depending on gender. As they aren't usually family-loving creatures (i.e. they are social, somewhat, but tend to veer away from staying life partners) have 'ritualistic' times of the year, (as do certain animals on Earth which), 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).<br/><br/>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. The planet is located in the milkey way, on the crux-scutum.
