PMU contains several regions, or different areas with their own levels for Pokémon, special items, dungeons, and activities.
So far in PMU 7, there are 4 major regions:
- Exbel - The first region added, and the first region the player encounters. It contains the first town as well as many weak dungeons for new players to train in.
- Winden - The second region in PMU. Contains stronger dungeons than in Exbel and provides great training for stronger players.
- Tanren - The third region that is mainly focused on higher level Ground- and Rock-type dungeons. It is relatively stronger than both Winden and Exbel. Many high-leveled players train here.
- Tanren Undercity - An extension of Tanren, accompanied with exclusive items often in demand and mid-game training.
- Archford - The fourth and relatively strongest region to be released to date. The highest leveled players come here after obtaining Surf and it includes some of the most adventurous dungeons.
