You could use what I would call "hearsay". Basically secondary or tertiary characters of the story providing information without giving too much away through common small talk. Example: - Protagonist: I heard that the Fluffy Munchers were heading into town. - Random Person: Oh those nasty munchers always mess everything up around here. No good has ever come of them. No mention of specific actions, but the sentiment is still expressed. Lace this into multiple "small talk" conversations and you will impart to the reader that this group is disliked by the general populace and are most likely up to nefarious things behind the scenes.
