North-West Lesion

Vacuo City

One of the largest cities in Lesion. It doesn't have a Pokemon Gym, but it does boast the region's only Contest Hall as well as a Park, the Pokemon Fan Club, and the Lesion Museum as well as a Pokemon Center and Mart.

Route 8

A slightly rocky area leading 24 miles up to Serenity. Many Hikers find it worth their while to walk the area's trails. [Wild Pokemon: Machop, Makuhita, Hitmonlee, Hitmontop]

Serenity

A town located in the rocky flats before Route 10. It has a Fighting Dojo, Pokemon Center, TM Shop, Move Reminder, Pokemon Mart, and the Serenity Pokemon Gym.

Route 16

An excrutiatingly long 78 miles trek through the Lesion wilderness. The Pokemon in this region are hardy and tough, and as such only Trainers with at least 7 badges are allowed Passage.

Route 17

One of Lesion's three Cycling Roads. Route 17 is a fairly well-known attraction among Cyclists, and the downhill ride to Route 8 gives a fair jolt of adrenaline to those racing their friends down the 6 mile slope.

Atlas City

The second of 'The Big Three' cities in the Region, as well as being the Lesion Capital, Atlas City is famed for its casinos and bars. It has dozens of Pokemon Centers and PokeMarts, boasts the Battle Tower, Name Rater, Atlas City Department Store, and a weekly attraction in which Trainers can rejoin with the Gym Leaders they defeated in the past and perhaps have a rematch. Most Lesion Regional Events are held here.

Route 10

An 18 mile stretch of land across an open flatland to the north of Serenity. Half-way through it branches off into Route 11. Several Trainers can be found battling against each other and even battling the wild Pokemon as they anticipate their upcoming Gym Battle. [Wild Pokemon: Luxio, Pikachu, Magnemite, Electrode, Dedenne, Ditto, Tynamo, Mareep, Stunfisk]

Route 11

Cycling Road #1. Route 11 branches off of Route 16 as a 6 mile downhill slope. Some Cyclists test their mettle by riding against the force of gravity towards the top.

Beacon City

One of the largest Cities in Lesion. It has several Pokemon Centers, the Lesion Power Plant, a Music Recording Studio, several bars and nightclubs, as well as three PokeMarts, several apartment complexes, and the Beacon City Pokemon Gym.
