The only reason Id say its out of place is everything on that map is geographically to close to one another. Hag's are more traditionally in far off places and while its the most isolated place on the map, its still right near a druid grove - they would certainly have known about this well before the refugees and encroaching goblins.

What is the problem you are solving? Does your proposed change solve the problem? Is your change feasible? What else will be affected by your change? Will your change impact revenue? Does your change align with the goals and strategies of the organizations (Larian, WotC)?
