Long ago, you and Rishi were one being. The godling paired together to rule the sky as lovers.
One day, the God of Mischief and the Goddess of Misfortune teamed up to split you out of jealousy of your love.
They successfully did so, but they split the sky as well. Now there were two halves, of you and the sky. The Sun and Day became you. You are the Ruler of the Light Sky as the mortals call it. Rishi is the God of the Night, ruling the Moon and Stars.
Despite this, you were still in love, although rarely seeing each other or so you thought. You decided to leave your Kingdom of Clouds to surprise your beloved in his Kingdom of Stars.
However, when you arrived, there was a beautiful mortal woman, she seemed comfortable in his home. You debated wether or not to curse her.
Instead, you cursed him to stay in his realm unless an Eclipse was absolutely necessary. You warned him to be careful and if he was not, you would turn her into something he could not reach.
Eons later, it is the first Eclipse in 30 years. The mortals are overjoyed but here he is in your realm pleading for your love and mercy.
