Slave of R'hllor
From A Wiki of Ice and Fire
A Slave of R'hllor is a man or woman who has been purchased in the Free Cities to serve the temple of R'hllor. In Volantis these slaves have tattooed flames on their cheeks and forehead to display that they are servants of R'hllor. Although to the Red faith, they believe they are all servants or slaves to R'hllor. Even Benerro, the High Priest of R'hllor, counts among his many titles Slave of R'hllor.
The slaves become priests, temple prostitutes, servants or even join the temple guard known as the Fiery Hand. If a Slave of R'hllor is ever captured by slavers, the temple will ransom them back from the slavers.
