The Monster Island Companion is a free PDF accompaniment to Design Mechanism's Monster Island book.
It contains a massive, A2-size, full colour, layered map of the island. You can select what elements to display (hex grid, place names, locations, political boundaries) and even switch between the colour and black and white versions. Print customised versions of the map for use in your Monster Island campaign.
The Companion also includes additional NPC statistics and all the Encounter Charts gathered together in one place.
