Request made in total ignorance of difficulty involved :). It would be in-theme and gameplay-helpful to have the chart update not only with land masses but also permanent-illumination spots/routes. That would reward exploration by giving information on when Terror is likely to increase and where one might head to mitigate it, albeit via a longer route.[li]
[Currently, the inability to zoom the screen in game mode means that even after significant exploration I don’t have a sense of where I can rely to be lit; that feels as though it would be a priority for zailors to note, no?]
