The Dolyahri are a pre-warp, arctic-adapted vulcanoid species from the planet of Dolyahr. At present their cultural development level is considered to be roughly analogous to the early Renaissance period of Earth.
The Etrynarian people were displaced from this population nearly a century ago and are still genetically identical to the Dolyahri. However there remains notable areas where Etrynarian culture has been forced to adapt to their new circumstances, such as a significant decrease in inter-house warfare and the abolishment of the practice of slavery.
