Oh come on… That map is stylized at best and BS at worst. It has no scale indicator, for one thing, and the relative positions of the landmarks doesn’t correspond to what we know to be true in game.
We already have an accurate in game map. The overgrown ruins are not located between the grove and the blighted village. The grove and the toll house are far closer than the grove is to the overgrown ruins. The tea house is closer to Selune’s temple than it is to the fishing village.
I think the hand drawn map is meant to be reminiscent of BG1 & 2’s travel maps. It’s designed for flavor rather than assessing travel distances.
