The Khel

The Khelish people are a race of ammonia-based humanoids from the planet Khelvan.

Khelish Biology
The Khelish people are one of the more unique races of Orii, being that they are primarily ammonia-based due to the conditions of their homeworld Khelvan, a Class 10 world, the rarest class to find. Due to this, most planets of Orii posses inadequate atmospheres, atmospheric pressures and native biospheres to support the Khel people, so few planets have only been found capable of supporting them.

Due to their nature, they are also incapable of eating food most other races could eat just fine, even more severe than the Kadravi dietary limits. Foods from argon, or carbon-based races would be at best inedible, and at worst poisonous, most suffer from immediate and intense allergic reactions that can often be fatal, so it simply isn't worth the risk of testing it.

Due to their traits listed above, as well as another factor, the Khel must wear highly sophisticated environmental suits co-designed by themselves, Neraavian scientists, as well as Krux'Han scientists. The Khel must take extreme caution when in combat, or any other potentially risky or harmful fields of work or activity, since a suit tear wouldn't be good.

Within 3 minutes of a suit breach, they would succumb to Stage One of Carbon Poisoning, which would render them quite light-headed, disoriented and off-balance. At stage two, roughly 5-8 minutes in, depending on the Khel, they would start to lose vision in their eyes as the ammonia deprivation began to set in. By 10 minutes in, at Stage Three, the air pressure would dry out and crack their skin. In Stage Four, the final stage, they would likely slip into mix of carbon-poisoning and ammonia-deprivation induced coma shortly there after around 13 minutes in.

However, there is an even greater risk they take when removing their suits. Their homeworld, Khelvan gave rise to the incredibly potent Khelvanic Plague, a disease to which the Khel are immune but the other races are having difficulty vaccinating against due to it's biologically non-compatible nature to their own biology, which will be further elaborated on here. If a tear occurs, immediate decontamination of all surrounding areas is required to avoid possibly spreading the disease inter-species, where it may be impossible to cure.

Uniquely, number of digits one each hand can vary from three to five among the Khel depending on your bloodline, and it isn't considered uncommon to see one with more than five digits on each hand.
