Lumati

The Lumati are a sapient spacefaring humanoid species which made first contact with Humans in 2259.

Biology
Not much is known about their biology except that they seem to require the same environmental conditions as most other humanoids, and they can safely consume tea.

Culture and society
Lumati culture is strongly centered on the idea of evolution by means of survival of the fittest. They believe that providing assistance, medical and otherwise, to those they regard as inferior would get in the way of natural selection, and prefer not to interfere with the natural development of other races, neither to help nor to hinder them.

Lumati ambassadors are accompanied by servitors known as "translators", which speak in their name, as the ambassadors themselves would consider it shameful to communicate with "inferior species". The relationship between master and servitor is referred to as a form of intracultural symbiosis.

Prior to making contact with Humans, it never occurred to the Lumati to isolate less-favored sections of their own population to prevent them from intermingling with the more socially successful ones. Once they observed social stratification in Human society, the Lumati came to admire it and agreed to form an alliance with Humans, on the grounds of them being not so different.

Lumati value tradition and seal alliances by having sex.
