Terran (The Stranger)

Terrans are a Human-like species inhabiting Terra, an Earth-like planet with three moons in the same orbital period as Earth, only located on the other side of the sun, unknown to Humans.

Biology
Terrans are externally identical to Humans, presumably internally identical as well, with the only known difference in physiology being the fact that all Terrans are left-handed, as opposed to Humans being commonly right-handed, but not entirely so.

Culture and society
Terrans, while having many developments that mirror that of Earth, primarily developed Western nations, follow an ideology known as the Perfect Order, which has created a planetary society built around working in harmony, serving the greater whole rather than the individual. While the Perfect Order appears to have been implemented with a benign goal of creating a planet-wide sense of family after a devastating war, the enforcement of the Perfect Order involves a totalitarian state where anyone with dissenting ideas is reconditioned, executed, lobotomized, or implanted with incurable terminal diseases. Government officials in grey double-breasted suits are known to handle the enforcement, scrutinizing their subordinates closely, sending out pro-Perfect Order messages, organizing pep rallies supporting their ideas, and monitoring others electronically, often making announcements to the public through speakers installed in public areas. In addition, Terran culture had become very restrained as to comply with the Perfect Order's guidelines, including banning public concerts, religions, and any history book covering events prior to the Perfect Order's creation, while other aspects such as the consumption of alcohol are also targets of elimination. While Terran culture and freedoms have been stripped away or tightly controlled, poverty and many once-negative aspects of society are known to have been eliminated, and Terran space capabilities were greatly improved. Terran soldiers, organized under a government division known as the Department of Protection, are known to wear entirely black uniforms with no visible distinctions of rank, and have been seen functioning as policemen. Terran civilians are known to receive welfare under a program known as Citizen's Welfare, with each individual in the system designated by a letter followed by four numbers. For reasons unknown, the Terran language is exactly like English, as is their clothing and architecture, while their measurement systems mirror that of the imperial system.

Technology
Terran technology is known to be almost exactly identical to modern Earth technology in both function and design, although there are occasional differences, such as phone booths bearing no dials and needing no money to operate, instead having an operator connect the line to its target. Terran space-faring technology is advanced enough to reach Earth, although the program has not pursued such a goal yet.
