Fernia

The Fernia were a race of humanoids that used to inhabit a forest  village centered around an ancient tree. Unlike most mortals, Fernia  tend to be proficient at the use of elemental magic and have a higher  average lifespan. However, in terms of physical aspects they do not  differ significantly to regular humans and up to the age of adolescence  they age normally. Characteristics that tell them apart from regular  humans are their long, feathered ears and the seasonal change of  pigments in their hair (and sometimes eyecolor). 

The Fernia  worship a goddess named Gaia and believe that their aptitude towards  elemental magic and their long lives are a blessing from their goddess.  Moreover, they believe that the sacred tree at the center of their  village is a manifestation of their goddess. At the point of time where  most events of my character's story take place, the Fernia are believed  to be extinct and most mortals treat them as characters from fairy tales  and myths.
