Atrele does have duties as a priestess aside from "bang everything that moves". She engages in magical research, leads ceremonies, and gives the occasional sermon. Here, we have Atrele in her formal robes... mostly formal. The corset is a personal touch, but most priests will customize their robes in some way. Why have a uniform that doesn't make you happy?

Or others happy. Look at that cleavage.

Original piece (FA) by citrusfreebies and Atrele belongs to me <3

And thanks to Bunbun, for getting this for me~
