A Sister's Pledge

Please, <name>. I know it is Arugal you're after. I swear on my father's memory I will help you take him down. But I must beg you... Anya is completely innocent, we cannot leave her with these savages. Help me rescue my sister and you'll have me at your side when you face Arugal. I know the den Anatoly spoke of. We'll find it on the other side of this hill. Let's go, my sister's in danger.
