This is the standard/pin from The Black Company when they took on the commission from Soulcatcher. The design on the medallion isn't mine but I did modify it slightly to match the description from She Is The Darkness.

"... the silver skull exhaling golden flames that originated as Soulcatcher's personal seal. The skull was not human because it had exaggerated canine teeth. No lower jaw was present. One eye socket was scarlet."
