Captain Bathis:
Good, I like young people with courage and determination! Guard Vent is heading up the search party for Sakum.
He's already over at Windmill Hill.
Lucky for you, you're able to teleport directly to Windmill Hill from here. Just arrange for the teleport with the gatekeeper at the middle of town. When you arrive, tell Vent that I sent you. I will reward you for the hard work.
