Appearing as mutilated humanoids with large heads, Nihilids are terrifying to encounter. They are thankfully rare.
To all space explorers, rogue traders and Federation colonisation and expeditionary force officers!
Thirty new alien species have been discovered. You are well-advised to inform yourselves, as to engage these entities correctly, without risk of harm to yourself or to the interests of Terra.
Ten of the described species are human in origin, yet modified to such a degree that they no longer need to be considered human.
Another ten are civilisation-building aliens competing with Terra for available space.
The final ten entries are remarkable life forms that display sapience, without using it to create civilisations. Caution is advised.
The Glassenheim Foundation is a relict of the Petroleum Era, a technological hold out and a holder of terrible secrets.
A hostile race discovered through dimensional boring. The first encounter with the violent and nomadic Tarxan occurred in Neo-Constantinople of the Eurasian Alliance, hence the Turkish/Central Asian rooted name.

A blue green jewel, Beta Delphini II, home of the turtle like Chelonians. The world is old, and bears many scars, the craters from orbital bombardment and high power explosions, rings of dust and debris that were once starships, habitats, and fighter craft. But the world below remains tranquil, its wounds covered with blue seas and green forests.
A member of the Cynopterid race
This humorous short fiction piece was inspired by a late night chat with a couple gamer friends about how alien cultures would possibly interpret some of the more "colorful" aspects of our society.
A race of beings actually IS invunerable while in adolecence. They age, but cannot be killed. A miniority of the race (1 in 20) does not become invunerable, but rather becomes immortal at some point in thier adolecence, and ceases aging while being vunerable to death in all the normal ways. Another minority (also 1 in 20) Permanatly becomes invunerable after adolecence, but ages twice as fast as the race normally does. There is no known way to test for which of the three traits an individual manifests and the three traits cannot mix, as they are tied to the same gene, as it were.
