A previously reliable Soldier has gone rogue.
She is not working for heaven. She is not working for hell. She does not stand beside others. She is instead using her impressive array of skills and songs to look after hre own fortunes.
Digging will reveal that she recently came into possession of a lupine fetish (and the spirit of individualism within has come into possession of her). Should either side attempt to retrieve or recruit the Solder or her new Ethereal Patron, the pair shall use all means at their disposal to remain free.
