Though I would normally not care too much about the sufferings of the humans, there could be business to be made through trading with this village since they use the spirits of the forest in their crafts.
Since the only place that would be able to dispatch a punitive request to deal with the Orcs would be the governing town Guild, I went there to offer our services, for a just reward suited to saving their entire village of course. I don't like charity unless it benefits me.
