The PCs traveling along the road/path/trail begin to hear a low droning sound. As they approach they find their path obstructed by hundred of thousands of droning insects. Locusts swarm though the air, feasting on the grass and plants. Passage will be slowed, but the insects pose no threat to the party, aside from being crunchy and disgusting underfoot, climbing into pouches and eating exposed food goods.
Recently, agents of a necromancer's guild known as the Guild of Morticians have been seen slinking around the graveyards in the metropolis of Jeffsport. They have been seen with many small undead creatures, leading to speculation that someone may be digging up the corpses and selling them to the Guild of Morticians. The Jeffsport Civil Authorities Office and various splinter groups thereof, including the famous Blue Lampsmen (the Jeffsport city guard), have issued a bounty of 100 silver pieces for information leading to the capture of whoever is selling the corpses to the necromancers, and a 30 gold piece bounty on any member of the Guild of Morticians.
