Map

Note: This page is vastly incomplete, and many links will be created/rewritten/moved as Regions and their respective Rooms are found.

The world of Rain World is enormous. It is comprised of 12 distinct Regions, which are each made up of Rooms- anywhere from a dozen to 3-dozen Rooms can be a part of one Region.

Each Region has its own challenges and theme, and Sub-regions- simply put, when multiple Rooms share a theme, or motif, they are understood to be grouped together, and so each group is its own Sub-region. In these Sub-regions, there are individual Rooms.

Some Rooms themselves can be multi-screened, like Rooms on the surface.

In the event that a Room is multiple screens, an image showing all of the screens will be provided under each Room's Wiki page.

Below is a rough map of the regions, and how they connect with each other. Credit to reddit user QuiteSomeBiscuit

In-Game Map
In-game, the Slugcat uses the Memory Map, which is obviously based on memory. After a while, the slugcat will forget older parts of the map and remember new parts, even after death. Certain areas don't show up on this map, like Scavenger Merchant rooms.
