The way magic works in my world is runes. Some runes especially the basic variety have a story behind them. The culture my story starts off in is matriarchy and has a reverence to the rune of warmth/fire they live in a particularly cold environment. The second story is about a patriarchy society that lives in a blistering hot area they takes reverence to the rune of ice/cold. They both believe those runes were the first runes and built their religions based of those concepts. Their god/goddess is ìṣúdudu the god of cold, family, and survival. Ashara the goddess of warmth and love(romantic).
ìṣúdudu creation of magic- Drought plagued the land, In the desperate attempt to save his family Alao left his village to save family. He faced many trials . Running across the Savannah, facing dangerous beast, and bearing the storm of sands. While on the journey he found his wife,who foolishly followed him she was to be taken by the heat. Alao begged someone, anyone to help her. ìṣúdudu with all his power created the first rune to save his wife. A chill wrapped around them almost freezing . ìṣúdudu declared his creation to be Good.
Ashara creation of magic*- A Frigid winter plagued the Land. In a foolhardy attempt to save his village a man left. A women of the named Commodia followed him for he was her lover. The women faced many trials Frigid tall hill, dangerous Beast, and the storm of knives. She found her love,but he was to be taken by the ice. She begged anyone to help him. Ashara with all her power created the first rune to save Lover.A warm almost burning heat wrapped around them. Ashara declared her creation to be Good.
Sorry for that wall of text. My Question is how can two different religions with very different philosophies, Gods/Goddesses and are on the opposite side of the world from each other , Create such a similar story of magic?
