Famous among the core pantheon, are the representatives of the Sun and the Moon, the twins, Aurelion and Fiona. Born of a trist between Grimnir and a missing titan goddess Lotus, their existence was hidden even from Grimnir in a cave beneath an ancient temple on an island hidden at the bottom of the sea. It is rumored that the Four Sisters witnessed the birth of these new gods, not knowing their true identities, but drawn to their place of birth. Upon seeing the divine creatures born, radiant and gleaming, the Four Sisters knew they were destined for greatness, but had no idea that they were, in fact, their half siblings. The titan goddess begged them to keep their location secret and they swore to protect the beautiful and blessed twins.
When they were but a few days old, Aurelian was playing by the river in the cave when a great monstrous serpent came crawling out of a crevice. The serpent was the serpent god Python who, sensing the power of these children, intended to eat them up to wound heaven. Aurelian begged his godmothers for a weapon to slay the beast and, hearing his cry, Soffia told Pyra to fly to the sun and retrieve for him the bow of the primordial sun god Helios.With the flaming bow, the boy wounded the serpent and sent it slithering back. His failure to slay it may doom the world as it is said the serpent will one day return to end the world with the aid of the other serpent gods.
The next threat was another titan, Tytyos, sent by the titans themselves to find their mother Lotus. Tytyos had been a spurned suitor of the twin's mother and intended to take her back as his bride. When he saw her with young Fiona, he flew into a rage and attacked her viciously. He was a brute so large that to save his mother's life, he was transferred to and birthed from the earth itself, creating a great wound still in the sea. Aurelion was too far away to help so Fiona begged for help from their godmothers. This time it was Terra and Delphina who heard her cry, Delphina diving to the bottom of the sea to retrieve the bow of the primordial moon goddess Luna while Terra attempted to drag Tytyos back into the earth. With the bow in hand, Fiona made quick work of Tytyos and Terra dragged him broken body back into the earth from whence he came. But it was too late for Lotus, who, as she lay dying, told the Four Sisters that her children were the true heirs of heaven.
The sisters feared for the child gods, that their mother may grow wrathful at the existence of the sweet twins, and tried to hide them from her. But their efforts would be in vain.
Grimnir discovered them by the grim prophecy of the god Null, who he had created from the body of Mim, when Null told him he saw two futures: the sun and moon sitting on the throne of heaven and the sun and the moon slaying each other. The prophecy at first confused Grimnir as the titans of the sun and moon were long dead. So he asked Mim the Whisperer. He was told that the sun and moon had been born and that his children hid the secret. Grimnir felt betrayed and, gathering his might, summoned his children to heaven. It is said that upon seeing their father's face, so full of disappointment, his daughters remained resolute. Save poor Terra. Terra fell weeping not at her father's feet but at her mother's. She pleaded that she not kill them. Kleeona was flummoxed. The other three revealed the truth that they had hid their half siblings from Grimnir and Kleeona to protect them. Grimnir was stunned this time. He looked to his wife. Kleeona stood up from her throne and demanded to go to the cave. The daughters pleaded for her to show mercy but she was firm in her command. Grimnir was already gone.
He went to find his children and protect them from Kleeona. He went to the save, searching for them, but he was barred from entering the cave as his daughters had used their spells to prevent all men and monsters from entering after the attacks of Merrshaulk and Tytyos. This did not stop Kleeona. Inside she would find the twins still mourning over their mother's body.
Grimnir waited by the cave entrance for his wife and when he did he cried tears of joy. For Kleeona did not leave the cave alone. She came out holding the hands of each child and became the stepmother of her husband's twins from that day forward.
There are many stories told of these children who took up the mantle of the sun and moon. Aurelion would become the radiant master of the Sun and all the beauty it touches. He became the patron of music, poetry and the arts. He would know many lovers and quickly became the favorite son of his father. Fiona instead chose a more aesthetic life, vowing chastity, being the protector of women and enemy of men who would abuse them, and occupied herself by hunting beasts (not just beast-like men). She is often depicted with a torch as she, like the moon, provides light in dark times.
