"We are the descendants, the fortunate, the ones gifted with the knowledge to pass on what we know, learn, see and do."
a Leyron proverb.
The Leyron are considered to be unique as they are one of a very few known species to have developed a written language long before they developed a spoken or sign language.

According to the scrolls, the Chronicles of Leyron which are named after both their author and the supposed creator of their written language from whom they take their name as a species, they were a primitive nomadic, hunter, gather society when the god like being who was his father visited this world. He met and loved a young woman, Leya, fathered him and taught him until he was a man at which time his father returned to the stars never to be seen again.

Leyron claims in the scrolls to have created their written language with the help of his father. He narrates in pain staking detail all of the lessons, experiences and knowledge that his father imparted to him as well as all that he learned and experienced over his long life.

Based on the information available in the scrolls and the archeological evidence it would seem that the creator of their written language lived approximately 4,302 years ago.

The rest of their history is fairly peaceful, free of wars, conflict, internal strife and marred only occasionally by the random destructive nature inherent in the weather and gradual evolution of any planetary mass.

Eventually they developed space craft and made the first step towards exploring their solar system. At this time they encountered a battle damaged Romulan Warbird which had wandered close to their system and detected their test flight. This first meeting was stressful, as they learned of an ongoing conflict between them and the Saurian Empire.

They assisted the Romulans by providing them with some much needed materials and they returned the favor by providing some basic technical data that would improve the performance and safety of their primitive space craft.

Soon they learned that the Romulans had started the war and that they were not the friendly benefactors they had portrayed themselves as. This caused much concern and for the next 73 years they lived in fear that they might return as conquerors.

During this time they learned of the Federation, the Klingon Empire and the various conflicts between them and the Romulans. It was only when the Federation negotiated the creation of the Neutral Zone that would divide their area of space from that controlled by the Romulan Star Empire that they could truly relax as their world was on the Federation side of that zone.

Shortly after this they sent a delegation to the Federation and after some lengthy negotiations they were accepted into the Federation.

By the time of the Dominion War they had become fully integrated into the fabric of the Federation, with countless millions of their people scattered across the width of the entire Federation.


Their world has been divided up into 23 regions, each of which selects a council of 23 elders who oversee and control the local government. One randomly selected member from each council is always at the central council which is called the grand council. They can be replaced at random by any member of their own regional council. This Grand council governs the planet and the people as a whole.


On average they stand 5’4” to 5’11” with average builds.


As with most intelligent humanoid species they have a very complex system with specialized organs, and unique hormones, chemicals and enzymes. They are typical humanoids with most of the physical, mental and biological medical problems that seem to plague most humanoids.


As a species they seem to be prone to age related mental health issues and while medical science has been able to assist they still have a long way to go. Other than this they seem to be susceptible to a wide range of phobias and other mental health issues. On average less than 20% of their population seems to be affected.


The Chronicles of Leyron are a series of 4,823 scrolls detailing the life and teachings of the divine being credited with the creation of their written language. According to their beliefs he was the son of a god like being who visited their world over 4,000 years ago and a native female. These scrolls are preserved in the capitol and are considered to be their greatest treasure.


They have a confusing and sometimes illogical series of tales and legends regarding both the creator of their written language, his father and mother. Many of these stories have some small connection to one of the scrolls of the Chronicles of Leyron.


For the most part they seem to have a very laid back and organized society. Communities are well laid out and have plenty of facilities for recreation, education and fitness, especially as the quality of life has improved over the last 100 years.

There are continuous work projects to upgrade, improve and maintain all of the infrastructure needed to support both their communities and their population as a whole.


Great strides have been made in this regards over the last 100 years as the influence of their being members of the Federation has exposed them to countless different types and styles of music, instruments, art, sculptures and other forms of artistic expression.

So much so that evidence of this off world influence has crept into and influenced almost off of their newer creations and styles of artistic expression.


They have a number of interesting customs, one of which is their greeting towards others of their own species. This involves facing each other at about a 2 foot distance, placing the palms of their hands against those of the person facing them and reciting the first 21 words from the very first scroll of the Chronicles of Leyron.


They have a number of government funded research and development facilities as well as a fully developed educational and training system. Still even with this they tend to be behind most other Federation member worlds when it comes to their current level of technological ability.


They are fairly self-sufficient but have managed to take advantage of their being members of the Federation to develop and maintain a number of long and short term trade deals that have gone a long way towards improving the quality of life for all of their people.


They have no military of any kind and never have. However they do have a fairly effective worldwide police presence that also assists with emergency issues.

Federation Intelligence Files

One of their major subcultures developed a written language long before they developed any spoken or sign languages. They are the major known exception to the rule that most cultures develop a sign or gestural language before a verbal one.

Kathryn Janeway once studied the gestural idioms of the Leyron, which she found more comprehensible than the non-verbal language of the Tak Tak.


Both Memory Alpha and Memory Beta were used as references as well as the following TV episodes TNG: Loud as a Whisper and VOY: Macrocosm.

According to the Star Trek Encyclopedia (3rd ed., page 281), the sign language M-9 was originated by the Leyrons.
