The Burning Soul collection contains two premium cosmetics for Sienna Fuegonasus: the Flame Within hat and Maven's Cindergarb skin.

The cosmetics can be used on Sienna Fuegonasus’ Unchained career.

About the cosmetics:

Flame Within - Hat
Naught kindles a flame like the soul of its conjurer ... but once it takes root, beware.

Maven's Cindergarb Raiment - Skin
This gown has clearly been too close to a flame ... but did that flame burn without, or within?
