Pinwheel
It is the twenty-seventh century, and humanity has rallied under the flag of the United Nations in order to join the Coalition, a multi-species alliance working together to defend their borders from hostile alien races.
The 'Pinwheel' is the largest and most strategically important military space station in human territory, a place where humans and aliens rub shoulders, living and working in close proximity. Tempers fly and passions inflame as disparate cultures are forced together, all while an interstellar conflict rages around them.
