Escort Lakota Windsong from the Darkcloud Pinnacle, and then talk to Thalia Amberhide at Freewind Post.
Arnak thinks we're going to be married... but after I declined his offer he came back that night and kidnapped me. My brother tried to stop him, but Arnak was too strong. He... he slew my brother and then brought me here. My poor brother...
<name>, could you escort me out of the Darkcloud Pinnacle? Please... I need to get back to Thalia! She must be worried sick about me.
Thank you, <name>. Deep in my bones I knew that she would find her way back to me. She told me of your bravery and how you helped her escape. These items belonged to her brother. I know she would want you to have them.
