Featuring some of the members of the Triumvirate, from left to right:

Humans - A lively new member of the Jun-Mei Cooperative, with the overall purpose of the United Nations now being diverted to communicating with aliens, they have become quite widespread the moment space travel was achievable for everyone, with them being found even in Uzea and Actas space. Soon enough, it's quite uncommon now to find non-humans with human names as a result of this diaspora.

Jakul - Amphibians that despite being part of the Uzea Alliance, would find themselves being quite a boon for them due to the fact they are the alliances economic, legal, and medical powerhouse. The are often found on Mespah worlds as a result and are close allies with one another.

Stuko - This species lives on the edge of Actas space, and are often seeing themselves as somewhat autonomous of the empire as a result. They integrate well in a number of societies due to a large amount of trade going into and out of Imperial space going through them.
