The Veritans are a very peculiar species, which look like small elongated creatures with a pair of prongs which can cling onto a humanoid's face. They are almost completely inert and totally mute when on their own, but once clinging to their hosts they start speaking aloud any kind of statement as long as it's true, or widely perceived as true. They apparently do it involuntarily, but the damage it causes can be enormous as all sorts of unpleasant truths tend to come out.
