Walkthrough tips, Discussion of Campaigns [Heroes 5]

I'm playing a mission for Haven, as Isabelle. It's mission 5, I think. I found the Tear of Ashi and built everything. Godric needs to find Nicholas, but where should he look? I've searched the entire map, and he's nowhere to be found... Where should I send Godric? I tried to eliminate the guards at the outpost to reach the Red City, but they keep defeating me. I understand that I can't proceed without Nicholas. Can you tell me where Godric should go to find him?
