The average male weighs 130 pounds, and female about 90. Psychologically these people are intellectually sophisticated and possess a strong sense of rational thinking. They are passionately curious about the nature of things and how they work. The Alyssians evolved a sophisticated scientific culture early in their history, which shaped their modern society to a great extent. This was greatly assisted by their early reliance on farming and sailing, both which required a high degree of organization and social stability.
Alyssian culture has a very strong sea-faring tradition.
Their planet being so covered in water, Alyssians developed astronomy and ship building techniques early, enabling them to reach distant landmasses in the middle of vast oceans. Early Alyssian settlements were quite isolated from each other due to the geography of the planet, so when contact did occur between two groups, it was usually a very happy occasion. The traditional suspicion and aggression that normally follows such encounters in most species was simply not present in the Alyssians. Therefore, culturally, Alyssians love meeting strangers. They used to practice lengthy greeting rituals and feasts during such occasions, and some of these traditions have survived to this day in the extensive greetings that Alyssians use with people they see everyday.
