The beggar can be found in Old Hillsbrad Foothills.
If you move over to him, he will ask if he can clean your shoes for one copper as well as copper for grog. He will ask you to give him silver and calls you a friend.
He says "Spare a copper, you wont need it son, the end of the days are near". He will say "Please sir, I have three children. Did I say three? I HAVE TEN CHILDREN". He will also say "Will work for food".
