The Maze, drawn in level order
Contributed by @nepure · Covers the Maze region on the normal route
How to read the chart
Every map is drawn as the artwork you actually see when you walk it, so you can match where you are standing to the chart without reading a label. The red lines join map edges that genuinely connect, and the circled numbers run from 1 to 12 in order of increasing enemy level — that is what the Japanese subtitle under the title says. START marks the map the region begins on, at the bottom of the chart.
The numbering lines up with the map codes in the official atlas, so circled 2 is MZ02, circled 5 is MZ05, and so on through the region. BOSS marks the three arenas, which are the last three by level rather than the last three along any single path.
Where it leads
The Maze is a hub rather than a corridor. The three panels across the top are the exits, labelled in Japanese as the routes to the Ice Field, to America and to the Amazon, and all three are reached through the round chamber below them — the one with the compass floor and the three coloured doorways.
That chamber is the reason the chart is worth having: from it the region fans out three ways, and the drawing shows which branch turns where before you commit to walking it. The three arenas sit off to the sides rather than on the way to any exit.
