Karp is an NPC in the Nashkel area. She can be found in the vicinity of the southern farmhouse on the east side of the river (1600, 3050). She will complain about how bad farming is and that she and her family will soon be broke.
Come this time next year, we'll all be living in the endless slums of Athkatla.
Trivia: Her name is probably a pun on the verb "to carp."
