Nadya makes sure to correct the map for Beck so he is holding north to the top. Um, that way Beck, otherwise I think you would be heading home instead.
Looking at the map you are gong to skirt the forest a bit more as you head north. Then you start to angle your way north by northwest till you hit a tributary river that eventually runs into the lake that sits by Whitethrone.
Good luck finding my uncle. He is good at hiding if he doesn't want to be seen. He may hear about you before you find him. Be careful of who you talk to and try to keep it from people that you are not from around here. Perhaps Xanxan can alter your clothes as you go to make it look more local.
Xanxan, you can make 5 craft checks at DC 15 to alter clothes for people. A success indicates that that individual will get a +2 on disguise checks if needed to appear local. Jetro doesn't need any as he is a local.
