There is already a Discussion open for the exact same Topic. You need to start A quest called Harboring a Fugitive by either finding an NPC called Ahmri in Harvest Valley or Talking to the Marefolk Chieftain all the way South in Hawkethorne and then locating Ahmri. If you get stuck you can also consult the wiki its usually faster and more reliable. https://wiki.smutosaur.us/CoC2/Main_Page.
