The mysterious elven pantheon of Dragon Age mythos has been distorted over the centuries, as the Dalish elves (also known as "The People") passed stories from one generation to the next. Though they were considered to be godlike and responsible for many of the worlds great wonders, they did not take part in the creation of Thedas or the Fade.
Also known as the Evanuris, or "the creators," the elven pantheon is comprised of nine beings, five male deities and four female deities. Each one of them is responsible for specific aspects of Dalish life and culture.
The Evanuris
Elgar'nan - The God of Vengeance
Also known to the People as the All-Father, Elgar'nan is a god of protection and vengeance. He's the eldest child of "The Sun" and is said to have overthrown his father, becoming the central deity of the pantheon. Husband to the goddess Mythal, the pair watch over the People together.
Mythal - The Great Protector
Mythal is a goddess of love, justice and motherhood. Wife of Elgar'nan, she is mother to the twins, Falon'din and Dirthamen.
Falon'Din - Friend of the Dead, The Guide
Falon'din is said to be a god of death and fortune, responsible for guiding souls through the Fade after death. Twin brother of Dirthamen, he is the eldest son of Elgar'nan and Mythal.
Dirthamen - Keeper of Secrets
Dirthamen is master of secrets and knowledge, which he gifts to the People. Twin brother of Falon'din, he is the second son of Elgar'nan and Mythal.
Andruil - Goddess of the Hunt
Andruil is a great hunter, who bestows her gifts of nature to the People. She is sister to Sylaise.
Sylaise - The Hearthkeeper
It was Sylaise who taught the People the domestic arts, giving them the gift of fire to keep their hearths burning. She also taught them healing arts and magic that would keep them safe. Sylaise is sister to Andruil.
June - God of the Craft
June taught the People the art of crafting weaponry, like bows, arrows, and knives, so they might hunt the animals bestowed upon them by Andruil.
Ghilan'nain - Mother of Halla
Ghilan'nain is the goddess of navigation. The precious halla (white deer-like creatures) she bestowed upon the People pull their aravels, guiding them through the land.
Fen'Harel - The Dread Wolf
Known to the People as a trickster god, it was told that Fen'Harel betrayed both the Creators and their rivals, The Forgotten Ones, locking them away in deep slumber in an act that brought about the destruction of the elven paradise of Arlathan and the downfall of the elves.
The Forgotten Ones
Opposite to those the elves called the Creators, the Forgotten Ones were the dark side of the bright gods who gifted the People with so much. Bringers of disease, fear and malevolence, not much is known about them aside from the fact that, like the Creators, the Forgotten Ones are said to have been tricked by Fen'Harel and locked away in the Abyss. The elves have even forgotten most of their names, save for Anaris, Gelduaran, Daern'thal and (possibly) Xebenkeck.
Whether or not Fen'Harel can be considered one of the Forgotten Ones is debatable. According to legends, he moved freely between the two factions, manipulating them both to his own ends.
May the Dread Wolf Take You
According to Solas (who is later identified as Fen'Harel) in the Inquisition DLC Trespasser, the Evanuris were not gods in the same way as the Maker. They were incredibly powerful beings, similar to spirits or mages, who were closely tied to the Fade, where they existed. They communicated with the elves through rituals, some of which lasted for months at a time.
The Dalish thought their gods began to withdraw following the appearance of humans, which they believed severed their ties to immortality. However, Solas discredits this notion, claiming it was the creation of the veil which made the elves mortal. It robbed them of everything that made them who and what they were, according to Solas.
Solas also explains that the Evanuris and the Forgotten Ones were fickle and controlling, always fighting and warring against and among themselves. When Mythal (whom Fen'Harel considered to be the best of all the Evanuris) was murdered, he created the Veil and banished those who remained, claiming that giving them freedom would lead them to destroy the world in their lust for power.
Fen'Harel's actions and the fall of Arlathan resulted in the enslavement of the People by the Tevinter Imperium. Over the centuries, their stories became distorted, their language, history and customs faded, and their worship of the Old Gods was all but forgotten until Shartan fought beside Andraste against the Imperium and won a place of freedom for the elves: The Dales.
In Mythal's temple, which the player infiltrates during Inquisition, there are ancient elves who work tirelessly to practice the old ways and restore faith in their lost gods, most particularly Mythal. While the Dalish elves desperately try to restore their customs and keep to the old ways, so much was forgotten that their practices and worship remain distorted.
Fen'Harel will almost certainly play a central role in the upcoming Dragon Age 4, for he vowed to walk the path alone in an effort to tear down the veil and restore the elven people no matter the cost. What that means for the rest of Thedas is impossible to imagine. According to Solas, restoring the Elven Pantheon could mean the end of life as Thedas knows it, so its clear BioWare has big plans for the series' future.
