Deerfoxes are quadrepedal mammalians which resemble a cross between deer and foxes. They have glossy coats of thick fur and long fluffy tails like those of foxes, which can be almost as long as their body. Their head and skull shape is similar to that of a fox, although they possess antlers (or horn nubs as cubs). They have hooves like deer, and while their legs are short and canine in appearance as kit, as they grow their legs lengthen and begin to look more deerlike in appearance.

Deerfox reproduction is more akin to that of deer than to that of foxes. A female deerfox will typically rear a single or pair of kits (with triplets being especially rare but not unheard of).

Deerfoxes mature more slowly than natural deer or foxes, but go through the stages of growth. Deerfox young can be referred to as kits, pups, or fawns. When they are first born, much like newborn foxes, they are blind and cannot walk, but they shortly develop similar abilities to young fawns, developing sight and being capable of awkward and stumbly first steps. They gradually strengthen, and on the material plane will reach adolescense around the age of seven, whereup their antlers develop from minute nubss into their adult antlers. As deerfoxes mature, their antlers can be used to judge their approximate age, typically developing another prong per antler every two years.  Like reindeer, deerfoxes do not lose their antlers, and even female deerfoxes develop antlers (although their antlers tend to be smaller and less dramatic than in males). As they age, deerfoxes not only the develome their antlers, but also mature in a number of other ways which makes them appear more deerlike, including an elongation of their legs and neck, as well as a subtle narrowing and elongation in their facial structure which makes them appear resemble a whippet crossed with a husky dog.

Deerfoxes occur naturally in the Faewild, but their presence on the material plane is exceptionally rare. They tend to occur most commonly around places on the material plane where the border with the faewild is exceptionally thin, such as near Faerie circles, the intersections of magical leylines, or places of powerful wild magic. Their affinity for these places has resulted in them typically being found in places of truly pristine wilderness. They prefer temperate or arctic climates, often found in secluded forest glades, high mountain valleys, or arctic woods.

Although they posses fox-like faces, Deerfoxes are strictly vegetarian and leave almost no impact on their environment. They only drink water which is absolutely pure, preferring to lick the morning dew off leaves, but have also been known to drink from the sources of glacial streams and mountain springs or to drink the fresh rainwater which drips from the canopy. Their diet is similarly ascetic. They are known to have a sweet tooth, (especially as pups) enjoying berries, fruits, and tree sap, but generally eat grasses, leaves, nuts, pine needles, and pinecones.

As creatures native to the fae, Deerfoxes do not experience many of the typical seasonal changes which deer or foxes experience, but they seem to migrate and follow magical leylines to surges in wild magic. When on the Material Plane, Deerfox experience seasonal changes in their coats, shedding their summer coats for thick white winter coats.

Deerfoxes are social, semi-intelligent beings. They are monogamous and mate for life, with both parents participating in rearing their young. Generally, Deerfoxes prefer to live in migratory herds made up of multiple family units, and do not typically display and clear social hierarchy or territoriality. Deerfoxes are strictly vegetarian and despite their canine appearance, do not prey on any other beings. They tend to be shy pacfiists, preferring simply to avoid conflicts and using their keen natural and supernatural senses to avoid those who would seek to do them harm. If threatened and cornered and unable to hide, or if their young are endangered, Deerfox will defend themselves, but only insofar as is necessary to escape the threat and defend those in danger. The only exception to this rule are Displacer Beasts, which are known to hunt Deerfoxes, and which Deerfoxes treat with hostility and will attempt to drive out of their territory when they encounter them.    Finally, Deerfox are known to be naturally protective and good-natured. They have been known to act as adoptive guardians of the innocent, such as protecting children lost in the woods, and even seem to possess a sense of justice and obligation, repaying kindness with kindness.

Deerfox live in loose family groups, lacking a clear social hierarchy. They mate for life, and pairs typically raise a single fawn at a time. Deerfoxes are not territorial and do not generally display for dominance, and prefer to live in small herds, though family units occasionally detach from these herds and cross to others, and herds fuse and split fluidly.

Deerfoxes are wild, although their strong sense of empathy occassionally draws them towards kindred spirits, whom they can form strong attachments to which can resemble domestication. In such cases, Deerfox tend to act as benevolent sentinels or protectors, especially for the innocent and helpless. In such cases however, the Deerfox are not domesticated, but are more accurately described as being companions to their adopted wards.

Widely revered and respected, and possessing greater sentience than most naturally occuring animals, Deerfoxes are rarely exploited the same way livestock and are left to live wild. However, certain malevolent powers hunt them for various purposes. Deerfox horns and hearts have magical properties which can be used in certain profane rituals, while the death of Deerfox can be a key sacrifice or critical aspect of evil rites. Deerfox pelts are also regarded as symbols of wealth, power, and prestige among certain unscrupulous communities.

Deerfox more look very similar to foxes as kits, but for the nubs of their horns, but slowly their face shape changes to more closely resemble deer as they age and their antlers develop.

When they cross to the material plane from the Faewild, Deerfox tend to be found at high altitudes and near the poles. They prefer cooler temperatures, and feel most at home in temperate and evergreen forests.

Deerfoxes are semi-intelligent. They have good memories, develop unique personalities, and live in complex social groups with interpersonal relationships between members. Not only do Deerfoxes possess a limited ability to communicate with one another through body language and vocalizations, they can also communicate to a limited degree with other canines and cervids, and even are known to understand Common, Celestial, and Sylvan, largely through their incredibly perceptive emotional intelligence and sense of empathy.

Deerfoxes are highly perceptive, not only about the mundane world around them, but also of wild magic and emotional energy. Much like their namesakes, they have above average senses of smell and hearing and naturally, given their affinity for moonlight and twiglight activity and origin in the faewild, possess capable nightvision. Somewhat surprisingly, they also have a fairly refined palate which is capable of detecting even slight impurities in their food or drink.    Deerfoxes are widely renowned for their ability to sense variations in magical and emotional energy, with an intuivite sense for the magical currents which ebb and flow throughout the world and of the points through which the veil between the planes is thinnest and they can step through it. They can sense sources of strong good or evil, and can also detect the presence of powerful fae, undead, celestials, infernals, or arcane magic (though they have less experience identifying these, more rarely encountering them). Although they typically follow their senses along magical leylines while on the material plane, they are attracted to strong sources of good and repelled by the presence of evil. Addtionally, Deerfoxes have an innate resistance to being magically charmed.
