This system notebook provides blank map pages to detail 3 worlds using the icosahedral (20 sided) map projection style like found in classic Traveller. The notebook contains 3 global maps showing all 20 triangles on a two-page spread. It also includes 30 Continent scale maps, enough it detail each face of all 3 planets in greater detail. The book is saddle-stitched, so it can be opened flat. There are also pages to detail each world's unique details. See the other Albatross Hexbooks for other scale map pages, allowing you to zoom into even greater detail for your worlds.
