Final answer:
In the novel 'Gods of Jade and Shadow' by Moreno-Garcia, Xtabay returns Hun-Kame's eye. This action has mythological parallels in other cultures, where deities' body parts represent significant elements of their respective creation myths.
Step-by-step explanation:
In Moreno-Garcia's Gods of Jade and Shadow, Xtabay returns the eye of Hun-Kame.
The significance of returning body parts in mythology can be related to other myths, such as the Pan Gu legend, where different parts of the deity's body transformed into various elements of the Earth after his death.
Similarly, in Aztec mythology, as represented by the Sun Stone, body parts have significant symbolisms, such as the heart offerings to the sun and the creation myth of the five suns—the gods' body parts often embody larger cosmic principles or elements.
