How did Enyaba get the arrow?

Could you elaborate on the origin of the arrow that Enyaba possesses? Was it a gift from a higher power, or did she acquire it through her own means? Did she find it in a hidden cave or was it bestowed upon her during a sacred ritual? Is there any significance to the arrow that ties back to her mythology or background? I'm eager to understand the story behind how she came to possess such a powerful object.
