Rakori are a bipedal species with vibrant yellow skin and a biological affinity for arcanism. The center of a rakori's spine, in the small of their back, is surrounded by a collection of white orbs ranging from one to six. This group is referred to as a rakori's "nexus" and is the organ with which they store ardyr. Their lineage is divided into five coexisting bloodlines, each of which is signified by a distinct tail. Reproduction between bloodlines has a 100% premature mortality rate, and thus breeding between bloodlines is forbidden and shamed by rakori culture.
Warriorborn rakori possess multiple distinct developmental habits from their infancy. The infant will voluntarily afflict great harm on their own tail, attempting to chew on it (in a process called "tailing") or crush it. This will cause the tail to become bruised, scarred, and eventually, calloused and coarse. While tailing is painful, the biological instinct to tail is urgent enough that rakori psychologists continue to question whether agency is retained during the process. In addition, the infant will seek out and ingest metals. These metals are diverted from the rakori's digestive tract and diverted down into the rakori's tail. The effect of these combined habits is a hardened, heavy tail.
Warriorborn are given a special "coming of age" ceremony upon developing the ability to flex their metal-filled tails off the ground. This ceremony includes the process of permanently affixing metal bands intended to preserve the integrity of the tail to its bulky end.
As part of a peaceful species, warriorborn rarely employ their tails against others. However, the metal bands and the reliable and steadfast reputation of warriorborn give their bloodline symbolic power which is instantly recognized by other rakori and species familiar with them.
Shamanborn rakori are characterized by an incorporeal and intangible tail which is located on the paraspatial subplane. This tail consistently appears as "chopped" into disconnected segments which move together in the same way they might if each the tail was not segmented.
The consensus theory on the shamanborn tail declares that the tail serves as a method to connect the physical rakori to the nonphysical spiritual world. This connection manifests itself in the form of visions, divination, and necromancy. It is common for shamanborn as young as 14 to experience sudden, vivid hallucinations, accurately predict the future, and speak to the deceased.
Mageborn rakori possess an otherwise featureless tail distinguished by the presence of an additional nexus floating just past the tip of their tail. This nexus moves with the tail and is tangible, albeit slightly hazardous. As the rakori stores ardyr in this free-floating nexus, exposed arcane materials may cause volatile reactions upon proximity and/or contact. Non-arcane materials are unaffected by a passive nexus.
Due to their aptitude for maintaining ardyr flow, mageborn rakori are highly sought-after for ardyrological positions such as matrix custodian and xenoanalyst. While mageborn possess demonstrably equal average intelligence to that of other bloodlines, their affinity makes them prime candidates for research, development, and engineering.
Chakraborn rakori tails are muscled and sensitive, granting the owner superior balance and agility. The signature aspect of their appearance is a tuft of fur at the end of their tail. A chakraborn rakori also possesses a hyperactive nervous system, resulting in accelerated metabolism, higher energy levels, and high sensory sensitivity. Consequently, chakraborn often grow into physically demanding tasks of a wide variety, including athletics, labor, espionage, and specialist military practice. With little extra muscular development, the average chakraborn is capable of suspending himself off of the ground with his tail alone for short periods of time, but this ability can be trained with enough intensity to allow stronger chakraborn to hang from fixtures for up to three uninterrupted hours.
Artisan rakori are characterized by a stubborn insistence to be referred to as "artisans" as opposed to the conventional "artisanborn" as well as an extremely long, prehensile and dexterous tail which splits into two ends at the base. Artisans naturally develop the use of their tails during the same formative period as their arms and legs, thus resulting in an increased affinity for multitasking and a consistent bias toward efficiency. Due to self-propagated perceptions of somewhat demonstrable superior productivity, artisans tend toward haughtiness and condescension, seeing other bloodlines and species (excepting Akacians) as less capable contributors to society.
