Maddie's home of the Azim Steppe worships a pair of gods known as Azim and Nhaama. Azim is the sun, while Nhaama- his lover- is the moon. It's common understanding that the black-scaled Xaela Au Ra are born of Nhaama in Her image while the Raen Au Ra, with their white scales, closer resembles Azim. As a 'daughter of Nhaama', it was only natural for Madhuri to make use of a pristine scale from her tail as the core of the moon that she would build layers of crystal over to eventually become the final celestial body.

She has built a number of layers around the scale full of the fundamental tales of Nhaama, noted from a wiki entry:

Nhaama, The Dusk Mother, is the Auri goddess of the moon believed to have warred with Azim, the Dawn Father, in time immemorial. To settle their conflict, Nhaama is said to have created the Auri Xaela as soldiers to fight a proxy war against the Auri Raen created by Azim. However, the Raen and Xaela are said to have put aside their differences and learned to love one another, leading the gods to depart the mortal world and bequeath it to Their creations.

Oroniri tradition adds onto this, believing that Azim and Nhaama became lovers, but could not be together as they are the sun and moon.

Further, she has added her own fond memories of worship of the Dusk Mother growing up, as well as a number of old songs raised in glory of Her.
