I'm looking for Neoleth's assistant. I've been fanning out from the mushroom houses in a grid going form the coast to the river where the silt strider is. I've covered a good deal of the territory finding many ash spawns in the area west of the strider but no assistant. I'm tired of the search. Where have you guys found her or her body?

Also I can't get the New Source of Stalrim to continue. When I return to the Skaal village to tell the blacksmith I got the map, he just says generic things. He does have an arrow / carat over his head implying he should do something more. Did I need to more than croak the Thalmor guy & get the map & take it to the blacksmith?

Thanks.

Have you talked to Neloth's assistant? He will tell you to talk to Neloth's Mycologist, then a marker should show up after you have spoken to her.
Not sure about the other question. Maybe someone else can help.
