Ketyr

They are a species of subterranean carnivores, native to the planet Earth. It is unknown how the Ketyr came to be - very few scientific tests have been conducted on them, due to their reclusive nature.

Because of their underground lifestyles, the Ketyr are eyeless creatures. However, very old specimens can develop sophisticated eyes with a natural ability to function in extremely dark environments, needing a minuscule amount of light in order to allow for sight.

Eyed Ketyr are often referred to as "Alphas", since they have lived for the longest and are generally at the top of the social hierarchy. The average life span for a Ketyr is around 90 - 110 years, but some have been known to live up to 150; the older a Ketyr gets, the more intelligent is becomes - most Alpha Ketyr can even speak human language, as well as communicate using their own language, known as "Ketyrean tongue".

There are four stages of development for the Ketyr species; the first being the "Young Stage", which is from 0 - 15 years old. A baby will be given time to grow and develop its brain to a reasonable standard, where it eventually enters the "Gamma Stage"; they are the lowest within the social hierarchy, and serve mainly as hunters or workers, building nests within their respective communities. The Alpha stage lasts for 30 years, from 15 - 45 years old. The next stage of development is known as the "Beta Stage"; it is during this time that a typical Ketyr will begin to grow a blade-like chitinous protrusion from their right arms, replacing the hand altogether - this is a normal mutation, and is used mainly for intimidation purposes, but a Beta will use it as their primary form of attack.

Additionally, a Beta will also grow darker in complexion, and 'fill out' more; they become bulkier, and develop larger horns. The final stage is, of course, the "Alpha Stage"; this lasts from 70 years old up until death. During the last stage, a Ketyr will gain even darker complexion, their skin and chitinous armour becoming an incredibly dark grey; aside from skin tone, the most outstanding feature of an Alpha are the newly-formed eyes.
