My character's band had a successful gig but the whole time at this Halloween festival there were odd angry flare ups between people (including our Theurge and the winner of a dog show) that didn't make sense until we went deeper than basic Penumbral Senses. Turns out there's a big Bane called a Dissonant Gestalt (new to 5E AFAIK https://whitewolf.fandom.com/wiki/Dissonant_Gestalt ) dumping motes of negative spiritual energy over the festival goers.

There's also an interloping pack of Garou from the neighboring sept that we have to decide if we're going to ask for help since they're violating our territory.
