The Grey Warden Ser Ruth appears to have taken your forgiveness to heart and has found purpose with the stalwarts of the Chantry. She has requested resources to take the word of the Maker to areas where less able messengers might be threatened:
Inquisitor, the compassion you have shown has compelled me to act in your name. Where the Maker's word is absent, I can rekindle it. Where His light has faded, I can rekindle it. I will challenge the worst of Andraste's detractors and inspire where her chanters cannot go. And if I fall in her service, that will serve as well.
If she is determined to do this, equip her to do it. At worst, she strikes a blow in our name in some forgotten corner.
Ser Ruth took our rebuke to heart and has not pursued her self-destructive plan. It remains to be seen whether she can find a true peace with herself, but at the least she will not be dying in our name.
Ser Ruth was misdirected to areas we have already cleared of factions opposed to us. She disappeared for a time, but reportedly surfaced in the chantry in Val Chevin. She has requested long-term lodging. Perhaps that is a good sign.
Ser Ruth was sighted in a number of communities at the borders of our influence and apparently inspired a number of recruits to our cause. She then disappeared north, near suspected Venatori holdouts. We have not had confirmation of her survival.
