Publisher's blurb:
This battlemap includes 2 layers: the top layers, a skull island (40x40), and a cavern layer (45x33) that opens up into the right eye of the skull island. Each layer also has 3 variations: Skull Island during day, night, and rain. Cavern during day, night, and with a shipwreck inside of it (see preview)
The pack includes grid and gridless versions of all variations + large, high resolution print files in jpg format, as well as PDF files for tile printing if that's your kind of thing.
