Artemis 

Also known as Amarynthia, Diana or Cynthia (she is sometimes confused with Bastet and Selene) Common epitaphs are: Potnia Theron (mistress of wild animals), Kourotrophos (nurse of youth's), Locheia (helper in childbirth), and Agrotera (huntress).

The daughter of Leto and Zeus, and the twin sister of Apollo (she is said to have been born the day before her brother on the isle of Ortygia. After her birth, she helped her mother to the island of Delos and then delivered Apollo thus her tie to childbirth and protection of children). Artemis is the goddess of the moon, the wilderness, the hunt, plagues, healing, virginity, wild animals, childbirth and fertility.

In ancient times, she was often depicted with the crescent of
the moon above her forehead. She is classified as an Olympian and was a renowned virgin goddess. 

Her domain is the wild where she hunts and protects lions, panthers, hinds, stags and the Katagaria. She carries bows and arrows that are made for her by Hephaestus and according to some sources the Cyclopes.

She is a goddess of great contradictions. On the one hand, she hunts wild animals as her prey and on the other, she voraciously protects them from other hunters. She was said to aid women in childbirth, but then was said to shoot her arrows into laboring women to kill them as they struggled to bring their children into the world. Reputed to deliver illnesses like her brother, she was also considered a goddess of healing.

Protective of her virginity, she is known to kill any man who so much as gazed upon her or tried in any way to seduce or dishonor her. She even killed her nymph Callisto when Callisto was tricked and then seduced by Zeus.  

She is always portrayed as extremely possessive, especially of those things which belong solely to her. She tolerates no encroachments of any sort and shows her wrath to anyone who disobeys her. Even to the point of forcing Agamemnon to sacrifice his daughter Iphigenia to her after he killed a stag inside her sacred grove (although some versions of the story say the goddess took pity on Iphigenia and put a stag in place of the girl, then she took Iphigenia off to be one of her priestesses).

Her festivals are the Brauronia, which was held in Brauron, and the festival of Artemis Orthia, held at Sparta. During this festival,  young Spartan boys would try to steal cheeses from her altar. As they tried they would be whipped. The meaning of this ritual has long been lost and scholars can only speculate why they did such.

In the context of the Hunter Legends, she is a primary goddess who rules over all the Dark-Hunters.

When the Apollites were cursed by Apollo and then as Daimons turned against mankind, Apollo sought his sister's aid in handling them. For reasons unknown, Artemis went to Acheron (common belief is that he was a renowned Atlantean hero whose bravery had caused him to be spared when Apollo cast the city into the ocean) and convinced him to help her hunt down and destroy the Daimons who were preying on pregnant women and children.

Neither Acheron nor Artemis has ever disclosed the exact nature of their relationship. In many ways, they act as if the other doesn't exist. All that is known is that Acheron must seek her out whenever a Dark-Hunter wishes to reclaim his soul. Since no other Dark-Hunter is allowed in the goddess's presence, Acheron is often sent in to ask her questions or to clarify her orders.

She is ruthlessly protective of her army and of Acheron. Her affinity for Acheron is sometimes an aggravation for certain Dark-Hunters who can't understand why he alone is able to see her while any other man who dares such is put to death. She has placed her mark on all her Dark-Hunters and demands a sacrifice for each one who would seek his or her freedom.
