The Sun has many children, but most of all he loves his three daughters: Golden Sunshine, Misty Shadow, and his youngest, Bright Sunbeam. They lived free on the tundra until they saw a strong fisherman on Lake Seityavr.
Golden Sunshine claimed him first, marking his brow with gold. Misty Shadow laughed and tried to claim him with her cold song through the night. But when dawn came, it was Bright Sunbeam whose warm gaze revived the sleeping fisherman. He awoke to her rosy face and chose her, taking her to his humble hut.
Furious, the elder sisters complained to the Sun. Heartbroken, the Sun stripped Bright Sunbeam of her divine status but banished her sisters as punishment: Misty Shadow to guard the forest marshes, and Golden Sunshine to guard the stone mountain's treasures, forbidding them to harm the couple.
Bright Sunbeam became a mortal wife, learning to fish and sew. She and the fisherman had a daughter, Akanidi, who brought light to their home. Despite his wife's warnings, the fisherman went to the cursed Black Varaka swamp for birch bark and was ensnared by the transformed Misty Shadow. Forced to build her a hut and feed her and her monstrous children, the fisherman and Bright Sunbeam wasted away toiling for them.
The Sun, discovering their plight through his son Peivalke, sent Tempest to destroy the swamp hut. He transformed the disobedient Misty Shadow into the marsh witch Oadz. The freed couple returned to their lake home.
Later, the fisherman found a golden pebble—a fragment of Golden Sunshine's robe. Ignoring his wife's warning, greed consumed him. He collected more gold until it led him to the stone mountain, where Golden Sunshine trapped him, forcing him to mine gold endlessly until he was near death.
Bright Sunbeam, knowing he was in peril, went to find him. Before leaving, she gave her daughter Akanidi her severed little finger and instructions: to wear her divine robe and boots, light a fire on the mountain, and use the bone to summon Peivalke to take her to the Sun.
Akanidi did as told. Peivalke, mistaking her for her mother, took her to the Sun. Akanidi revealed her identity and gave him her mother's bone. In grief and rage, the Sun unleashed his storm children to split the mountain open, revealing Golden Sunshine surrounded by the bones of her victims. He transformed her into the underground witch Vagahe.
The Sun then took Akanidi as his new Bright Sunbeam. Vagahe, in her fury, sealed the mountain shut.
Thus, the wicked Vagahe roams for victims, and Oadz lurks in the swamp, both fearing the Sun's light and the gaze of Akanidi, who now shines warmly upon all living things.
