The Galaxy is inhabited by quintillions of individuals of many different species. These races make up the various powers at play in the galaxy, and include everything capable of higher thought including Sapient AI, Plantoids, and Humanoids.

• Humans - The ruling species of the GHC as well as the founding species of the GSC, born near the center of Major Sphere Amanillion. Humans are generally known for their lateral thinking abilities as well as their wide but middling range of acceptable living environments.
• Bhirni - A race of furred Saurornithoides with large, dextrous claws and medium length tails. They are expert swimmers and demonstrate an instinctual knowledge of fluid dynamics.
• Nixiti - Centaur-like humanoids which possess an upper body reminiscent of a baboon and the lower half of a rabbit. They rarely grow past four feet tall fully upright, and are known to be some of the galaxy's best pilots due to their natural reflexes.
• Pothon - Huge chemoautotrophic scavengers with a vaguely human body plan. Their hands are twice the size of a normal humans' and they possess four fingers on each, and they have no head, instead posessing a large, plant-like growth which they trim as one may maintenance hair or a beard.
• Pihitil - Small beaked creatures with bright, warm-toned feathers and six limbs that function as both graspers and ambulatory appendages.
• Zhyn - Eight foot tall panther-like quadrupeds with dark, UV-resistant fur and eyes capable of aiming in different directions at once. Their tails are tipped with dark green feathered plumage which splays out wide, and they have split prehensile tongues. It is said their singing voices are among the most beautiful to all the galaxy's ears.
• Renau - A large race of densely feathered Saurornithoides with forepaws and hind claws. Their forepaws are linked to their bodies with semi-vestigial wings and are capable of gliding short distances. Males grow up to twelve feet tall and females typically reach eight feet in height.
• Askraad - Bipedal lizard-like humanoids with large clawed limbs and prolate spheroid heads. They are capable of visually perceiving EM radiation from visible light to well into SHF frequencies, and rely on cybernetic implants they receive from birth in order to hear and communicate with sound.
• Hii - A race of huge bipedal polar-bear/saber-tooth hybrid-like creatures with four arms. Their upper set of arms are strong and durable with three fingers each, and their lower set of arms, which they typically fold into their fur and out of sight, are dextrous graspers with eight fingers each.
• Iuspex - Five-foot tall canines with soft, slug-like cerata that grow like a mane out of their backs. Instead of tongues they have long, multi-branched proboscis that fork more as they mature - adults may have dozens of forks in theirs. They will rapidly grow sick and die without regular cleanings from the Ruspex.
• Ruspex - Large, hollow carnivorous plantoids with thick fire-resistant bark. Their multiple oral orifices exhibit tremendous biting force and possess short tongues covered in long prehensile ciliae. Normally energetic, they grow lethargic and mentally dull when they go to long without the company of an Iuspex.
• Rinnegata - Sometimes also called Rinn, the Rinnegata are colossal stone-skinned draconic beings capable of surviving the void of space. They are omnivorous in the traditional sense, but can also consume raw hydrogen and a few heavier elements for sustenance. Rinnegata are born roughly eighty meters long and forty meters tall, but rapidly grow to up to several kilometers in length with a proportionally matched height.
• Nusti - A race of avianoid bipeds similar to owls, with long flexible beaks they use to pierce and drain fruit of its juices. They have wings for arms, with long prehensile feathers which act as graspers and also provide fine control of flight.
• Garaka - Large bipeds with thick, leathery skin and numerous sensory protrusions forming multiple necks and invdividual “heads”.
• Whark Species - Not one species but a collection of hundreds of others, there are too many species in the Whark Aviform Hegemony to list in a simple summary.
• Human Lineage Artificial Intelligence - Fully sapient artificial intelligence, with consciousness models more or less compatible with the mental-emotional model shared by most galactic sapients.
• NESTEC Lineage Artificial Intelligence - Fully sapient artificial intelligence descended from NESTEC's early AI creations which were not modeled after any existing sapient's consciousness structure. As a result, these AI tend to consider emotions and attachment as choices to be made rather than facts of life.
