The eighth book in the Albatross Hexbook series is designed specifically for mapping those pesky megadungeons. A good megadungeon requires repeated forays over the course of dozens of sessions, which can lead to a mapping headache if the party's cartographer isn't able to make it. With this notebook, the party can record their explorations in a single volume that can be handed off to be expanded as they delve further into the bowels of the earth. It features 38 pages of quadrille paper, each with an associated page for noting what is found in each room in an easy two page spread. Additionally it has 6 Type VI maps for mapping the area around the dungeon, and a Type V map for other details within the location's 6-mile hex.
