Humans are bipedial carbon based lifeforms that spanned out into the galaxy from the planet Earth. they are the extreams of everything we know from hate and love to evil and good. They seem to be the jacks of everything and masters of none. Insanely courious they seem to focus on everything at once accomplishing great things in short lifespans. Unlike many cultures among the known cultures even after space travel and the proof of other races they never stopped fighting among one another. Infact the diffrent cultures went into the stars and were then broght to heal in thier first interstallar war.
Right now thier planets and empire have been smashed by a xenophobic enemy and they are nomads among the stars trying to survive. Despite thier losses humans continue on fighting and trying to survive. If nothing else they have proven to be as stubborn as long as the stars burn.
