The Elthyri are a tall, lithe, astute and haughty species.

Basic Information


Elthyri are of typical humanoid appearance. They diverge from their human projenitors with heightened reflexes, greater cognitave functioning in regard to spacial awareness, lighter skeletal structure, and taller average stature.

Growth Rate & Stages

Elthyri reach physical maturity at about 47 years of age.  The majority of Elthyri adolecence is essentially identical to humans.

Ecology and Habitats

The Elthyr were fashioned for increased capabilities in zero-g environments.


Elthyr are pecieved to be unnaturally reserved and indifferent in social settings.  This tendancy perhaps results from their neural pathways being significantly altered from human norms.  While the behavior of an individual Elthyr can indeed vary from this presumed baseline, it is widely acknowledged that Elthyri often have difficulty connecting with non-Elthyri.

Additional Information

Average Intelligence

Elthyri often conduct complicated vector math in their heads for fun.  Their extreemly capable intelect is doubted by no one, especially amongst the Elthyri themselves.

Perception and Sensory Capabilities

Elthyren eyes are capable of seeing into the ultraviolet spectrum. This adaptation allows them to see many things that others cannot, such as some gasses, otherwise non-reflective objects floating in the void of space, magnetic fields in some sircumstances, and their vision is un-hindered in low light environments.

Civilization and Culture

Major Language Groups and Dialects

Elthyri typically speak Chant, just like humans and D'varth (another trans-human species).   They also possess a subtle private language called Elthen. This is comprised of clicks and whistles, or hand and body gestures.

Interspecies Relations and Assumptions

The Elthyri have nothing against other species.  They just know that they are better than other species.  It is just the way that they were designed.
