Human
biology
Humans are the most well known species with a robust physiology. They are bipedal mammals and generally strong, fast and agile. They reach physical maturity at around 18 years old. Then they enter the workforce or continue their education for a profession. The average human lifespan is naturally about 79 years, but advanced biotechnology and cybernetics has substantially increased human lifespans. Humans primarily reside in a colonized region colloquially known as "the Bubble", which contains about 19,000 star systems. They originated from the single-star system Sol and the terrestrial planet Earthin the Orion-Cygnus Arm of the Milky Way.
As it has been throughout recorded history, mankind is not very prone to agreement over ethical, political, religious, and economic views. It remains this way today in the 34th Century, with the realm of human-colonized space held by numerous groups under various ideals, some benevolent and others not quite as much.
There are three major factions known as galactic superpowers and several Powers in human-colonized space. The Federation is based in Sol and is a representative-electing democracy. The Empire is based from the system of Achenar and is a hereditary monarchy. The Alliance is based from the system of Alioth and is a confederation of independent systems working cooperatively. Powers are powerful individuals or organizations who strive to control inhabited space for their own agendas in Powerplay. Each Power can control a vast amount of systems that is aligned to both major and minor factions. In addition to the three galactic superpowers and the powers, there are also many minor factions. The faction with the highest influence within the system will usually be the controlling faction of that system. System control falls on the faction that owns the controlling station. The government of a system is ruled by a controlling faction and if that faction is an anarchy no laws will apply in the system.
