His father tried to eat him as he was being born, but he was saved by a rat who ran off with him and brought him up.
The rat taught EL-LAL sacred lore and how to construct a bow and arrow. Several years later he emerged to become a people’s champion and destroyed many bad giants.
When he got tired of it all he just sauntered off to we know not where. And what became of the rat? We know not. Did it have paws with opposable thumbs? Was it responsible for the rat race?
