Sunday Matinee Crawls: the Hive Opens

You planned for a peaceful night of rest after hours of travel. The inn was well stocked with provisions and the local villagers enjoyed a night of entertainment; listening to stories about your travels and adventures, songs about the dangers, and participating in some games of chance, giving the villagers a chance to win some of your hard earned coin.

In the aftermath of the earthquake, a small park collapsed revealing a cave system hidden below the town. Echoing sounds of chitters and chirrups began to exit the new opening. Worry swept through the town, everyone acting uneasy about what might lurk below. Will the party bring ease to the town and enter the unknown depths?
