Padani

The Padani are a humanoid species native to the planet Chara of the Zura system, a homeworld that is now almost uninhabited after ecological catastrophes. Almost universally the Padani have learned to embrace immense caution and a form of almost institutional paranoia with regards to the universe around them. Their collectible governing polity is known as the Interstellar Commonwealth.

Biology
There is very little to separate the Padani externally from humans, one of a few few such species, like the Betazoid. However, the internal structure and chemistry are quite distinct from each other.

Social
The basic social unit of the Padani is the extended family - grandparents down - rather than the nuclear family. The customs regarding guest-rights and hospitality are very important in Padani culture. Officially, the primary language is an artificial construction based on the predominant languages at the time of global unification, with strong consonant-vowel pairings for clarity. Within the home, however, nearly all individuals still speak pre-unification languages as their first language.

Homeworld
Chara, the homeworld of the Padani, is the second planet out of six that orbit Zura, a typical yellow main-sequence star(add specific type here later). The next planet in is a Venusian hot-house, the next planet out is an icebox - both planets are about the same size as Chara, which is about the same size as Earth. Chara does not have as many large continents; instead there are three dozen masses approximately the size of the South Asian subcontinent  on earth. In additional, island chains and atolls are plentiful. The largest open ocean is relatively small by the standards of M Class worlds, at approximately the size of the Arctic. Due to the ecological catastrophe of a bitter war that destroyed many cities, the planet is no longer densely populated by the Padani. Instead it has become an ecological preserve for an active terraforming effort.

History
The Padani have suffered numerous near-miss potential extinctions; from augment crises to AI to almost-nuclear war to barely averted asteroid impact to ecological catastrophe to near conquest to other more exotic things. This has left a mark on their collective psyche, resulting in a drive toward survival via redundancy, thoroughness, and preparation. the Padani have been warp-capable since the early 21st century yet rather than ranging widely, they focused heavily on exploration of their local sphere. As a result their local region is possibly the most thoroughly charted of all known space. This led to an astoundingly complete exploitation of the local region over the next two centuries.
