The Two Breeds of the Raksura
Arbora: Arbora have no wings but are agile climbers, and their scales appear in a variety of colors. They have long tails, sharp retractable claws, and manes of flexible spines and soft "frills," characteristics that are common to all Raksura. They are expert artisans and are dexterous and creative in the arts they pursue for the court's greater good. In their alternate form they are shorter than Aeriat Raksura and have stocky, powerful builds. Both male and female Arbora are fertile, and sometimes may have clutches that include warrior fledglings. This is attributed to queens and consorts blending their bloodlines with Arbora over many generations.
The four castes of the Arbora are:
Teachers - They supervise the nurseries and train the young of the court. They are also the primary artisans of the court, and tend the gardens that will be seen around any Raksuran colony.
Hunters - They take primary responsibility for providing food for the court. This includes hunting for game, and gathering wild plants.
Soldiers - They "guard the ground" and protect the colony and the surrounding area.
Mentors - They are Arbora born with arcane powers, who have skill in healing and augury. They also act as historians and record-keepers for the court, and usually advise the queens.
Aeriat: The winged Raksura. Like the Arbora, they have long tails, sharp retractable claws, and manes of flexible spines and soft frills.
Warriors - They act as scouts and guardians, and defend the colony from threats from the air, such as the Fell. Warriors are sterile and cannot breed, though they appear as male and female forms. Their scales are in any number of bright colors. Female warriors are usually somewhat stronger than male warriors. In their alternate form, they are always tall and slender. They are not as long-lived generally as queens, consorts, and Arbora.
Consorts - Consorts are fertile males, and their scales are always black, though there may be a tint or "undersheen" of gold, bronze, or blood red. At maturity they are stronger than warriors, and may be the longest lived of any Raksura. They are also the fastest and most powerful flyers, and this ability increases as they grow older. There is some evidence to suggest that consorts of great age may grow as large or larger than the major kethel of the Fell.
Queens - Queens are fertile females, and are the most powerful and deadly fighters of all the Aeriat. Their scales have two brilliant colors, the second in a pattern over the first. The queens' alternate form resembles an Arbora, with no wings, but retaining the tail, and an abbreviated mane of spines and the softer frills. Queens mate with consorts to produce royal clutches, composed of queens, consorts, and warriors.
