Answer:
The figurative language in this poem is May it be the shadow's call will fly away.
Step-by-step explanation:
This is figurative language because the shadow is calling and we know this is personification because a shadow is nonhuman meaning that it can't talk or do anything.
My other answer is May it be when darkness falls. I'm not so sure about that but I think the shadow's call will fly away is the best answer.
