The map associated with the adventure, " La máscara del Oni " ( Mask of the Oni ), is a high-quality, double-sided fold-out poster included in the adventure module. It serves as both a navigational tool for players and a detailed visual aid for Game Masters as characters venture into the dangerous Shadowlands .

: The reverse side focuses on the central location of the adventure, the ruins of the fallen Daylight Castle . This side typically includes two types of illustrations:

The map features two distinct sides designed for different gameplay needs:

: One side provides a zoomed-in, detailed view of the southern territories of the Emerald Empire. It prominently features the lands of the Crab Clan , the massive Kaiu Wall , and the immediate northern reaches of the Shadowlands . It highlights natural barriers and key strategic locations in this contested region.

A that "peels back" the walls to reveal internal rooms and layouts, allowing Game Masters to track party movement and manage encounters within the castle.

This map is intended to be used alongside the included in the physical adventure pack to help visualize combat and exploration in the hostile Shadowlands environment.
