The Interspecies Dominion's world-classification system lists Earth as a deathworld. Any being foolish enough to explore a class 10 and above planet can only do so through the exercise of extreme caution. According to the Corti Directorate, Earth is class 12. Factors include: its many predatory species, highly varied climate, high gravity (1.43 times the galactic standard), and particularly virulent microbiology. A few dangers examplary of the planet are: tornadoes, earthquakes, wolves, bears, fungi, salmonella, and Clostridium tetani. Earth is of particular note for being the only deathworld to host a sapient species, humans.
A Few Races:
Gaoian
Human-sized angry fluffy space-racoon-bear-dogs. Evolved on a class 9, so they have a similar outlook on life.
Allies of humanity (more-or-less).
Corti
Arrogant, frail little gray men that genetically engineered their race to be intelligent. They try their damnedest to control their emotions.
Vzk'tk
Mildly dimwitted blue giraffes, but very populous mildly dimwitted blue giraffes. Herbivorous with herd instincts, tend to defer to their cousin-species, the Rrrrtktktkp'ch.
Rrrrtktktkp'ch
Giraffes with way too many arms. Cousins to the Vzk'tk, assuming the role of caretakers. More intelligent, but also far fewer. Tend to be solitary.
Guvnuragnaguvendrugun
Very furry giants with bioluminescent flanks. Pentachromats. Very deliberate and plodding, tend to take their time with anything, especially their language.
This roleplay is set in/based on the Jenkinsverse, a series of stories in the HFY subreddit. While helpful, it will not be necessary to have read through the main series. Each RP'er will be roleplaying a ship of independent aliens or humans or some combination thereof. The fleet has been assembled and hired to investigate things, explore places, and occasionally fight battles for a Corti information broker known as The Contact.
That's the basic premise.
