Rickard Gudbrand was so inspired by the image on page 123 in the Eternal Lies book (left) that he decided to do a similar thing on his own, to be able to give his players during the game. Then he realised that he’d have to update the map as the investigators travelled to different locations, and possibly in a different order after the initial chapter.
The result is a beautiful interactive PDF map with layers, which the Keeper can use whatever order the players decide to travel in, as each layer can be activated individually and then printed (it’s designed as an A3-handout, so some fudging might be required to print to US letter size).
The PDF-reader must support layers for it to work. As it is very much a spoiler to a big part of the campaign, Rickard has protected it with a password: the first word on page 376 in the Eternal Lies rulebook.
