the "HSED", or "Human Space Exploration Division", is a human organization dedicated to space exploration and the management of interactions with organisms from other planets; the HSED represents all humans, every human who travels in space works for them.

The "UG", or "United Galaxy", is the galactic confederation that unites every intelligent organism in the galaxy under a single system of government; every living organism that travels through space, including humans, is under the laws and jurisdiction of the UG.

Like humans, there are an overwhelming number of diverse intelligent organisms of all shapes and sizes in the galaxy, all with different languages and cultures; humans are the only primates while the other Intelligent organisms are reptiles, insectoids, avians, non-primate mammals, some vertebrates and other invertebrates, some with internal bone structure and others with exoskeleton, and the list goes on and on; there are stronger Intelligent organisms, coming from planets with greater gravity, or weaker ones, coming from planets with lower gravity; earthlings are the only organisms in the galaxy with the ability to sleep, what other organisms see as a pre-death state; earthlings also have one of the strongest immune systems in the galaxy, courtesy of their planet infested with bacteria and microorganisms; humans are new to galactic society, they are described by other intelligent species as predatory primate mammals; humans are in an advanced technological stage, they have a wider range of color vision than the rest of the intelligent species, a fifth finger on their hands and feet called "little finger" that other intelligent species do not have, larger and stronger ships with more powerful engines, weaponry and military structure more powerful than many intelligent species, and the only innovative technology and knowledge to replace flesh and body parts with technological and mechanical parts; furthermore, something that humans have that no other intelligent organism has is the ability to not feel pain when it is too much for the body and the small possibility of surviving brain damage; To communicate with each other, all intelligent organisms use a small circular device in the center of their chests called the "UG Translator" which is connected to the central language data base of UG network.

Safeworld: relatively safe planets for almost any living organism, perfect for life and survival.
Normworld: Planets with a medium level of danger, but where life and survival are perfectly possible.
Deathworld: worlds considered dangerous, with different categories of danger; Category 1 is the lowest level of danger, Category 5 is used for planets where just landing could kill anyone.
Earth is classified by the UG as a Category 3 Deathworld, this is due to the absurdly large number of dangerous bacteria and microorganisms and that the fauna and flora are aggressive and violent compared to other planets; Earth is not the only Deathworld planet with intelligent life, but it is famous and known as the "Disease Paradise" due to its beautiful but dangerous atmosphere and surface.
