MARS HUMANS

Martian Humans Overview :

Nobody can tell exactly why Martian Humans have developed such a strong lust for independence. Indeed, at first glance, nothing is really different between them and Earth Humans and the relationships have been fine for a long time. Everything was fine between Earth and the colony until Mars got efficient enough to meet its own needs without any help, in spite of the lack of resources. Then, Human history repeated itself once again: the colony wanted more independence, and Earth wanted to keep all the advantages without any concession. So the tensions began, grew and exploded.

One of the main character of the Martian Human campaign :

Captain Nilea Cortilliari (female, 27):
Nilea was born on Mars and her father was one of the first officers in the Martian army. He was previously a high ranking officer, a Commander in the UHF, the United Human Forces - the armed forces of Earth. His skills gained in the UHF helped him greatly in founding the core units on Mars and in organizing the planet's defences. Her mother was a scientist in one of the secret military laboratories, responsible for projects concerning new radar and detection technologies.

Both were well-honored and well-known people on Mars, but killed in a tragic accident when experimenting in their own private laboratory at home.

Nilea was their only child, and inherited the organizational skills of her mother as well as the technical skills and logical thinking of her father. She started as technical officer in the Martian army, but rose fast in the ranks until she was promoted to Captain and received one of the newest and strongest ships in the army to command, a corvette. She is not only ambitious, but will defend the Martian's rights at all costs, so she will certainly be a charismatic leader. As well as being open-minded, Nilea is also very sensitive to science, and as such she believes in the existence of other races in the galaxy. Since the death of her parents she has been ever so determined to learn everything she can in the army (both fighting tactics and special abilities) and uses her skills in eliminating possible threats to the planet Mars: she will never use a harsh word against a Terran, but is critical of the World Government and their opinion about colonies. It is hard to believe that she will ever join the Terran army, not even in the case of aliens invading the Solar System, as her home is Mars, so she most likely will defend the latter planet. She is currently under the command of Yoshimo Sakuzo, whom she sees as her idol and who she treats like a father, although she has never been courageous enough to express this feeling to him.
