Long ago in times that have now passed into myth, much was different in the newborn world. Moths the size of hawks once fluttered through the sky. The rings on the ringed planet cast a glow upon the face of the new moon. The molten core of the world flowed not only with lava but with magic. And human beings wept tears that were sweet not salty.
It came to pass that two were born upon the earth to the same mother, one right after the other. Twins were rare in those days. The brother was born first, only moments before the sister.
