Oath Howler

Sometimes the wind catches a profane oath as it's uttered, carrying it far away before the blasphemy can form a tortured eddy that repeats the curse again and again. Such winds eventually tie themselves in a knot and take on a sinister intelligence.

The unholy negotiations Abrogail I held with Hell deep in the Whisperwood spun off an untold number of oath howlers, most of whom haunt that forest and its skies to this day. Oath howlers delight in other creatures' profanities. A potential victim can distract the elementals indefinitely so long as the speaker varies their languages, insults, and intonation. If done artfully, a creature might sandwich a request between pejoratives and so earn an oath howler's morbid cooperation—at least so long as they continue encouraging the elemental with fresh profane oaths.
