The Map Guide's logic and the way it connects maps are our own.
Open it from the top bar and pick a map: the town sits in the middle with the small maps around it, and the joints on the small maps are portals.
Hovering a small map shows its branches. While a route is locked, the hover preview turns off so you can study the way.
Clicking a small map locks it, so you can clearly see how to get there from that area's town; click again to unlock.
The small maps also show their monsters, so you can see what to hunt there; click a monster to see its drops.
