The HSED (Human Space Exploration Division):

the "HSED", or "Human Space Exploration Division", is a human organization dedicated to the management of interactions with the UG, study and documentation of extraterrestrial organisms, and management of human travelers in space; they basically deal with the connection between Earth and Space, the relations between humans and non-Earthly species, and traffic in and out of the Earth.

The UG (United Galaxy):

The "UG", or "United Galaxy", is the galactic confederation that unites every intelligent organism in the known galaxy under a single system of government; every advanced civilized race in the galaxy that has enough technology to travel through space, including humans, is under the laws and jurisdiction of the UG.

Alien races:

There are an overwhelming number of diverse advanced civilized species of all shapes and sizes in the known galaxy, all with different languages and cultures originaly from their respective planets. Humans are the only known advanced civilized race of primates in the known galaxy while all the other advanced civilized races are reptile-like, insect-like, bird-like, non-primate mammals, and more. The concept of "sleep" is rare in the galaxy, there are only a few races that sleep and humans are one of them. If a living organism comes from a planet with strong gravity by UG standards, then that organism will naturally be strong compared to living organisms from planets with a lower gravity. Humans are in an advanced technological stage, with advanced spaceships capable of light-speed jumps equal to the spaceships of other advanced alien races. To communicate with each oher, all intelligent creatures use a small circular device in the center of their chests called UG Translators, which are connected to the language data base of the UG.

Planet Classification:

The UG classifies all planets in the known galaxy into one of two classes: Habitable Planets and Non-Habitable Planets. Habitable Planets are classified into one of fifteen categories based on its characteristics, parameters, and native organisms: from category 1 to 5, the planet is called a "Safeworld"; from category 6 to 10, the planet is called a "Hardworld"; and from category 11 to 15, the planet is called a "Deathworld". Deathworld planets are usually relatively rare and even rarer for them to develop civilized organisms, although they do often develop evolutionary nightmares in the form of living organisms that adapted to the harsh conditions of their planet in a terrifyingly efficient way. Earth is classified as Category-13 due to its gravity and planetary characteristics, but mostly because of its native organisms that are way more dangerous and hostile in relation to other planets with life. Living organisms native to a Deathworld are called "Deathworlders", so humans are called that because of the classification of the Earth. Earth's moon is called "Selene" by the UG and all the other races in the known galaxy, a name that was given to differentiate it from other moons. Planet with Category-13 or higher were just theoretical until Earth was discovered and classified, but Category-14 or higher are still just theoretical.

The UMS (Universal Measurement Sistem):

The UG has a simple measurement sistem called "UMS" or "Universal Measurement Sistem", its purpose is to unite all races in the same measurement system to avoid confusion. UMS units in relation to Human Measurement Units: 1 Meter is equal to 2 Krag, 1 Centimeter is equal to 2 CentiKrag, 1 Millimeter is equal to 2 MiliKrag, 1 Decimeter is equal to 2 DeciKrag, 1 Decameter is equal to 2 DecaKrag, 1 Hectometer is equal to 2 HectoKrag, 1 Kilometer is equal to 2 KiloKrag; 1 Gram is equal to 2 Krop, 1 Milligram is equal to 2 MiliKrop, 1 Decigram is equal to 2 DeciKrop, 1 Decagram is equal to 2 DecaKrop, 1 Hectogram is equal to 2 HectoKrop, 1 Kilogram is equal to 2 KiloKrop; 1 Microsecond is equal to 2 MicroKrics, 1 Millisecond is equal to 2 MiliKrics, 1 Second is equal to 2 Krics, 1 Minute is equal to 2 MegaKrics, 1 Hour is equal to 2 MacroKrics, 1 Day is equal to 1 SolarCycle, 1 Week is equal to 7 SolarCycles, 1 Month is equal to 1 Kio, 1 Year is equal to 1 Kuro; 1 degree Celsius is equal to 2 degrees Tora; 1 m/s is equal to 2 Dulk; 1 km/h is equal to 2 Dork.
