A Secret Passage!
Faren Markelhay has asked the party to clear out the Kobold Hall near Fallcrest. He suspects the kobolds that have become quite the nuisance lately on the roads around Fallcrest are coming from here. He will pay them 100gp if they succeed, and an additional 10gp per kobold head brought back. If the party can bring back proof from any other significant threats he will add another 50gp to the reward.
