"In all seriousness, this job I have for you is not all that perilous, but it is important. I need a unit to investigate dead cattle in the two nearby villages. Supposedly there are no signs of the beasts being killed, but dead they are, nonetheless. If you agree, and I would be grateful if you did, you would be doing a great deed for the king."
