Deor are nomadic Normal-type Creo with impressive stamina.
Deor are calm and non-aggressive toward other animals and cautiously curious around humans, sometimes traveling alongside caravans before moving on.
Deor is the base form from which eight different evolutions branch, one for each affinity.
Biology
Deor bodies adapt rapidly to new environments: nasal passages warm up icy air in polar climates or cool down scorching desert air within hours of arrival. Their hooves harden to grip ice and dig through snow or become soft and sponge-like to handle wet ground and mud.
Their fur coats are also integral in regulating body temperature. Their hollow fur helps them stay warm in extreme temperatures by trapping air for insulation. The same hair structure works to reduce heat absorption and improve airflow near the skin in warmer temperatures. Also, by raising or flattening individual hairs, they can adjust how much heat is trapped or released. The more their fur is exposed to intense sunlight and high temperatures, the lighter its shade becomes, allowing it to reflect instead of absorbing heat from the sun. This same hollow fur endows them with a buoyancy that allows them to swim across rivers and lakes with ease.
Both male and female Deor grow branching antlers, used not only for defense but also for display. Their eyes are uniquely attuned to ultraviolet light, allowing Deor to perceive food sources and predators even against blinding snowy or sandy landscapes.
Deor are herbivores with a specialized diet centered on lichen, which most Creo cannot digest. Symbiotic stomach microbes allow them to thrive on this otherwise inedible food source.
Originally native to cold, snowy northern regions, Deor have since spread to every corner of the globe. Rather than following a set migration route, they roam continuously, often traveling over 5,000 kilometers a year. If forced to remain in one place too long, Deor become lethargic. They wander alone but rarely feel isolated. Chance encounters with other Deor form loose, roving communities that constantly change in size. Older Deor who can no longer travel as far often act as community anchors.
