The Prime Fomori

The Tethra are echoes of the Sídhe, the third iteration of the Fomori, which consists of both male and female genders. They are the most plentiful of the Fomori, yet, they are just as mysterious as the rest.

Basic Information

Anatomy & Morphology

They are anthropomorphic, with two arms, two legs and an endoskeleton. Their skin is smooth but appears to be stretched tightly over their bodies, creating folds and lines. They are completely hairless and have slightly elongated necks supported by large trapezius muscles, which push their heads forward giving them a hunched appearance. Their bones also appear over formed, creating noticeable shapes under their skin.

Biological Traits

Males or often larger and stronger than females, with larger head formations; however, females are more flexible and have stronger immune systems since they bear children.

Genetics and Reproduction

They have intercourse like most mammals do, with a gestation period of about 9 months.

Growth Rate & Stages

The Tethra have a fast early life cycle. They reach adolescence within seven to eight years and adulthood within thirteen to fourteen. This is due to them being echoes of the Seraphim. Their old age is considered to be around the 800-year mark, at which point their skin becomes wrinkly and their forms become more hunched.

Dietary Needs and Habits

The Tethra are magivores, consisting off of magical energies which they can extract via meat, plants or through drawing in the magic around them.

Additional Information

Facial characteristics

Their faces are roughly human shapes; however, they lack eyes and ears and have to two slits for a nose in the centre of their heads. They have large mouths with lengthy tongues and large bulky teeth. Their heads also form elaborate shapes, with horn-like protrusions that extend from their craniums, and simpler and smaller forms that extend from their chins.

Perception and Sensory Capabilities

They have no eyesight or hearing, however, they have an incredible sense of smell, taste and an electrosensory ability that allows them to detect even the slightest movements. All their other senses are on par with most mortal races.

Civilization and Culture

Naming Traditions

The Tethra's names are based in their native language of Fomoir.

Major Language Groups and Dialects


The Tethra are echoes of the Sídhe, who emerged in the Void around the end of the war. The Void is a black soundless realm and so it's hard to determine the geography of the realm and where they came from; however, it is known that they call their home Fomora. Sometime during the start of the first age, at the end of The First War, the Tethra found their way to Domus where they encountered the Tuatha, starting a continuous conflict between the races.

Interspecies Relations and Assumptions

The Tethra tend to act aversely towards other mortal races, seeing them as alien and strange, on the other hand, other mortal races view them the same, leaving little room for any relational progress between the Tethra and other mortal races.
