Myrina was born when her mother, Echion, was Queen of the Amazon Jungle. She was raised as a princess and intended heir to the throne but with Echion's final breath she named Kagerou her successor. Myrina vanished from the Jungle for seemingly years but returned to visit her mother's grave where she reconnected with Scorch, who was raised thought to be her sister when in fact she was of another's blood but abducted by Echion.
Myrina faded in and out of the Jungle because she has always been in her mother's shadow.
One day, she took a political visit to the Valley but found herself interested in Lokii. In a game of illusions and magic they toyed with one another but she found herself more lusting of him than he was of her. It resulted in a child, Brynhild, which she initially treasured until shoving her away because of the memories it brought forth. In an effort to forget Lokii, Myrina avoided the meadow and Valley. Much to her dismay, however, she always found herself reeled in by their familiar games and teasing.
In her shame, Myrina came across Mrydon whom she bred with out of pity for herself and out of wanting to be adored. She never saw Mrydon again.
After returning to the Jungle again Myrina made another effort for a diplomatic mission to the Valley, but instead of Lokii she found Covet. His perception of the Jungle women intrigued Myrina and so she found him later on in the meadow. Once again forgetting her responsibilities in the Jungle Myrina put all her effort into her affair with Covet who she has fallen for (but refuses to openly admit). Nayl was borne of this new passion.
