Irina can be found near the Bridge of Sacrifice, on the Weeping Peninsula side. When you talk to her, she will ask you to deliver a letter to her father, Edgar, over at Castle Morne. You can agree to do this or refuse. Obviously, if you refuse, then you won’t undertake this quest. And, if you do, you will then make your way to Castle Morne, which is a ways to the south from this location.
