Atmosphere/Legends

During the height of the Empire's colonial period, a system of classification for Atmospheres was established. This system, which was afterward used throughout the galaxy seperates Atmospheres into four categories.

Type I Atmospheres
Breathable

Has approperiate levels of Oxygen, nitrogen, and Hydrogen to be breathable by Humans and human analouges. Some contaminants, or other trace gasses can have longterm detrimental effects. Most aliens can breathe Type I atmospheres. Planets with a Type I atmosphere almost always have some form of life.

Type II Atmospheres
Breath Mask Suggeusted

Usually has approperiate levels of atmospheric oxygen, and nitrogen. Due to lack of sufficient pressure, or contaminants, or trace gasses, these atmospheres usually cause detrimental effects of Humans, and human analouges over a shorter period of time. Many aliens can breath Type II atmospheres without any trouble, depending on physiology. Planets with a type II Atmosphere usually support some form of life.

Type III Atmospheres
Breath Mask Required

Due to either lack of approperiate levels of atmospheric oxygen, or nitrogen, sufficent pressure, contaminants, or trace gasses, a breath mask must be worn. For Humans, and human analouges these atmospheres cause immediate or eventual impediments, or incapacitation. Some alien species can breathe these types of atmospheres depending on physiology, and biology. Planets with a type III atmosphere, sometimes support life.

Type IV Atmospheres
Enviroment Suit Required

Can either be toxic, flamable, or non-existant, these atmospheres cannot be breathed by Humans, or Human analouges. If tried to breathe, these atmospheres would cause immediate incapacitation, or death. Few Alien species can breathe this type of atmosphere. Planets with a type IV atmosphere rarely support life.
