Thank you for your comment. You are absolutely right: a map is missing. We initially planned to have one and Björn came up with some really cool ideas (like using hazard pictograms for the locations to give players the possibility to make informed choices). But due to time constraints I decided to finish the text first.
We had a rough version already and maybe it is a good idea to provide it as is, to visualise the layout and give players (and GMs) a better understanding of the area. Thank you for the input.
