Elune is the most powerful Eternal of Azeroth and the only true goddess in the world of Azeroth—Warcraft RPG: Shadow & Light ranks her as lvl 85 healer. She avoids any and all types of combat. She appears before Night Elves disguised as a ghostly Night Elf female with a skin that glows with intensity. Her eyes are pure moonlight silver, and her clothing along her arms, chest, legs and head are adorned with silvery jewelry.
Elune has the ability of calming races engaged in battle by singing a song of peace at night, until sunrise. She can heal or grant a follower the gift of healing. She can also resurrect a dead creature. Elune has never made herself known to any living creature in the physical plane in a physical form. She appears as a ghostly-image in dreams or in her most adept’s mind.
Elune protected all living beings and let them grow and thrive. She would cast her calming influence over many races to avoid conflicts among races. Malorne, Cenarius and Elune helped the primitive Night Elves to evolve without falling corrupted to the arcane magic of the Well of Eternity for many centuries. Despite their attempts to help the Night Elves, Azshara and the highborne were corrupted by the magic of the well.
After the War of the Ancients, the Well of Eternity was destroyed by Malfurion. The catastrophic earthquakes sundered the middle jungles of Suramar and Zin-Azshari underwater, leaving an eternal scar of chaotic energies—a storm zone known as the Maelstrom. The sundering caused Volcanoes to arise and release lava and ash into the athmosphere. This period in history, known as the Sundering, at the end of the War of the Ancients, caused the world of Azeroth to enter a a darkened era. The ashes from volcanoes caused the athmosphere to block the Sun for 8 milennia.
During those milennias, Elune helped to heal the land and to nurture the world back to life. Most of the Ancient Eternals perished during the invasion of the Burning Legion, including Malorne, Ursol and Ursoc, Agamaggan, and others.
With help of her son Cenarius, she could heal the land, and 3,000 years ago, the sun was once more seen upon Azeroth when the ashes in the atmosphere extinguished. The trolls, humans and the recently awakened Earthen had barely survived the coldness and darkness of those 8 milennia with no sun.
Barely entering a new era of peace and land harmony, a new threat loomed in the horizon when High Elves taught Humans to wield magic. The reckless use of magic in the hands of some humans called the attention of the demons once more, resulting few milennias later into the second coming of the Burning Legion.
According to War of the Ancients: The Sundering, Krasus revealed to Malfurion that Ysera mothered Cenarius. We recommend you to read War of the Ancients: The Sundering.
UPDATE 9-21-05: Richard A. Knaak answered to Blizzplanet:
Blizzplanet: “War of the Ancients Trilogy reveals that Ysera is mother of Cenarius and lover of Malorne. Are Ysera and Elune one and the same?”
Knaak: “Elune and Ysera are not the same. Here is the explanation, per Blizzard, who did not wish any further elaboration in the novel at the time:
According to the Sundering, it is said that Ysera is Cenarius’s mother. However, Dungard the Earthen says that he thought Elune ‘birthed’ Cenarius.
Elune birthed Cenarius, but gave him up to Malorne because Cenarius was more a creature of the mortal world and could not be with her. Malorne, who had relations with both Elune and Ysera, knew that he could not properly care for his son, but Ysera’s love was so great for Malorne that she took Cenarius as her own. Hence being his mother (or adoptive mother).”
