Father Zantus, who was treating the wounded, notices your captured goblins and wound.

Ah, you're injured. Let me heal that. And he heals Vellichek's wound. And you've captured some prisoners. Looks like we'll get some answers now. Then he looks over your shoulder and his eyes grow wide. You follow his gaze and see that five goblins, one of which is one of the singers, have found the fuel the town intended to use for a bonfire after the festival and have set it to blazing. They begin making torches to use as weapons.

But it appears you have more pressing matters to attend to. Go, before the town burns to ash! I'll secure the prisoners and continue treating the wounded.
