The xana is a character found in Asturian mythology. Always female, she is a creature of extraordinary beauty believed to live in fountains, rivers, waterfalls or forested regions with pure water. She is usually described as small or slender with long blonde or light brown hair (most often curly), which she tends to with gold or silver combs woven from sun or moonbeams. The origin of the Asturian word xana is unclear, though some scholars see it as a derivation from the Latin name for the goddess Diana. References to where the mythological xanas lived are still common in Asturian toponyms.
Besides exchanging other women's children for their own, the xanas promise treasures and can be disenchanted. Some xanas also attack people and steal their food. They live in fountains and caves.
A xana can be a beneficial spirit, offering love water[clarification needed] to travelers and rewards of gold or silver to those found worthy through some undefined judgment. Their hypnotic voices can be heard during spring and summer nights. Those who have a pure soul and hear the song will be filled with a sense of peace and love. Those whose souls are not pure will feel they are being suffocated and may be driven insane.
Xanas are usually depicted in one of two ways. In one, they appear as young Nordic girls, very beautiful, with long blonde hair. This image is usually associated with xanas who possess a treasure or those under a spell. In contrast, in tales in which the xanas steal children and enter homes to bite or steal, the xanas are small, thin and dark-colored.
Xanas have children, which are called xaninos, but because they cannot take care of them—xanas cannot produce milk to feed their babies—they usually take a human baby from his cradle and put their own fairy child in instead (see changelings). The human mother realizes this change when the baby grows up in just a few months. In order to unmask the xanín, one must put some pots and egg shells near the fire, and, if the baby is a changeling, he will exclaim, "I was born one hundred years ago, and since then I have not seen so many egg shells near the fire!"
Tales involving xanas 
The stories about xanas can be divided into four broad categories. First, stories in which the xana has a child. In these stories, the xana switches her baby for that of another woman. Second, stories of xanas who suffer spells. In these stories, an act performed according to a secret norm can disenchant them. Third, xanas who possess treasures and riches. The xana may have acquired the riches accidentally, or through donation or theft; sometimes the human character of the tale obtains the treasure, but most of the times he does not. Finally, stories about xanas who are malicious. The most important tales of this category are those in which the xana enters a home through a keyhole; those in which the xana takes and enchants someone; those in which the xana transforms into animals; and those in which the xana provides a magic belt.
Xanas in Literature 
Cuban writer Daína Chaviano uses the xana motif in her acclaimed novel The Island of Eternal Love. When one of the characters encounters a xana while she is combing her hair, the dialogue between them will mark a crucial twist in the plot.
Kelley Armstrong's Darkness Rising series has what are believed to be three people who are Xanas. Resurgent members of this supernatural race due to genetic modification. Membership and abilities are expected to be confirmed in The Rising. Believed Members of this supernatural race are Hayley Morris, Nicole Tillson and the now deceased Serena. Given their powers believed association with water Serena's death by drowning is suspicious and raises questions as to who would want to kill her, and be capable of doing the deed.
