The Xyrillians are a peaceful warp-capable race.
They are a humanoid species.
They have an unusual physiology. They do not have a
metabolism based on water or breathe an oxygen-based atmosphere. They are
herbivores and will grow vegetation on the walls of their ships.
Their atmosphere causes most other species to
hallunicate. To prevent undesired side effects, visitors must be weaned off
their current atmosphere. This process can take some three hours to complete.
The males will carry infants to term. This is done in a
pouch on the upper chest. Impregnation can occur with only minor physical
contact. Humans and Xyrillians are able to mate.
Their technology was far superior then Humans in the
2150s. They had holodecks to simulate other environments.
