The plot in its most crude of forms is best summed up as so; a group of unqualified men and women take it upon themselves to arm against an opponent they do not know. By traveling further North, they have no one but their own developing skills and those of their companions to survive and adapt, seeking out the source of corruption and start the plot proper. From there, the actual effort to standfast will become the objective.
In the meanwhile, not everyone will be quite as they were, which all depends on action or inaction.
They all could very much fail, or worse yet, turn to the looming shadow. But, I hope this generalization is sufficient,
