First and only mortal-turned-god, and one of the most important Deities.

Vileyi appears to be slender, pale, young woman with long blonde or golden hair, with light, blue or violet eyes. Her face is slim, with prominent cheek bones. Her body, free from any scars caused to her in her final hours of mortal life, seems to emit slight glow.
Barefeet, never touches the ground. Hair moves with her movements, just as if it was in the water.

Unknown; even when she appears in her human form, her feet never touch the ground, which makes her look weightless.

Night, stars, moon and destiny

The legend about her and Aen made them a symbol of passionate and forbidden love.

Vileyi and Dehmai portrayed together are the symbol of day, night, life and death- balance.

Vileyi's biggest weaknesses seem to be the human traits that she kept after turning into immortal being. She seems to involve herself with humans and other creatures much more often then other gods do, because of her inability to ignore the pain and suffering of mortals.
She constantly breaks the rules other gods has set for themselves 'to keep the world balanced', which creates a lot of tension and conflict between herself and other immortals.

Vileyi seems to be one of the most active Deities in the universe, as a lot of her followers seems to have seen or felt her close presence. It is said that by praying at night, at ruins of old sacred buildings or by the lakes, you are most likely to be listened to and visited.

Creation of moon, stars and everlasting relationships.

Her parents were never mentioned in legends. It seems like there is only little information about her older sister, Valleryi, who seemed to be Vileyi's caretaker for the most part of her mortal life.

Long time ago, before Humans and Dragons made the Pact and created the borders, when nights were completely dark and were ruled by monsters, there were two sisters living in a small cottage, on the outskirts of the Helmsfirth village. Valleryi and Vileyi were their names- Valleryi being three years older. Both of them were known to villagers for their beauty and bubbly personalities, with Valleryi being the more grounded and responsible out of two, and Vileyi being more lively, and independent, not wanting to find a man to marry and settle down with.

One day, while getting water from the river, her path was crossed by a Dehmai, God of light and life, disguised as a human. He went down onto the earth to see how his own creations are doing and didn't expect to meet Vileyi in the forest. But once he started talking to her, and noticed her liveliness, he became fascinated with her.

For many days he was visiting her, hiding his true identity, allowing her to show him her community and their life; taste their food and observe their daily rituals. And everytime the sun set, he was dissapearing, loving Vileyi more and more with every visit. Until one day, he appeared, and she was nowhere to be seen.
Dehmai started looking for her, until he reached the cottage where her and her sister used to live in- completely burned to the ground.
Vileyi's lifeless body was lying under big oak tree. Someone, jealous of Vallereyi and Vileyi's life and energy, took advantage of darkness of the night, murdered them and destroyed everything they had.

Dehmai, devastated and brokenhearted, created moons, to light up the endless dark sky. Then, he broke the rule he set himself, and brought Vileyi to life, not as human, but as one of his kind.

From this point on, she is Dehmai's wife, the guardian of Moons and Stars, and writer of destiny.

Vileyi became immortal and powerful, and so everything seemed to go well. But soon she realized that gods loved differently then humans do, and Dehmai couldn't comprehend all of her feelings, therefore she was hurting.

Belief that destiny is written in the stars and is associated with Vileyi wasn't a thing in original writtings of Prophecies. It only became a thing after human and elvish cultures started mixing together.

"I'm ready to start the conquest of spaces
Expanding between you and me
Come with the night the science of fighting
The forces of gravity"

"Have you ever had
To be the one who sail away?
Have your heart torn apart
Feel your love float astray?
Do you remember all the sounds
When I found you by the lake?
And how the water seemed to call your name?"
