Sentient lifeforms in the Nexis Galaxy are divided into two categories, Alpha and Beta class.

Beta Class beings  have a highly developed brain, capable of abstract reasoning, language, introspection, and problem solving. This mental capability, combined with an erect body carriage that frees the hands for manipulating objects, has allowed Betas to make far greater use of tools than any other living species on Earth. Other higher-level thought processes of humans, such as self-awareness, rationality, and sapience, are considered to be defining features of what constitutes a “person”.

Betas are known for their desire to understand and influence their environment, seeking to explain and manipulate phenomena through science, philosophy, mythology, and religion. This natural curiosity has led to the development of advanced tools and skills, which are passed down culturally.

Betas make up the vast majority of the Nexis Galaxy’s sentient population. Humans are the most typical example of Beta intelligence and physiology. Many species share a similar design, with slight evolutionary modifications to suit their world of origin. However some Beta species from more extreme environments can still vary radically in appearance.

In exchange for their intelligence and ability to learn and adapt, their was a evolutionary price. Betas sacrificed strength, senses, and specialization, becoming adaptable but fragile creatures. Betas generally share feeling of mistrust and fear towards Alphas, the rare species which managed to combine intelligence with feral strength.
