In the country of Grath, there are two options for joining another city. One- completely fuse governments. Ex. Manhattan fuses with Brooklyn, Queens fuses, etc. etc. Two- create a jointed goverment called a Combined Metro. The three cities, Rivertown, Highland, and Shore City, (thus R.H.S) have fused to create the first Combined metro in the Grath City area. 

METRO STATS:

POP: about 70,000

BIGGEST CITY: Rivertown  

(AREA IN COLOR IS THE METRO AREA)

RIVERTOWN:

Rivertown is the third largest city in the Grath City area and in all of Grath. (behind Grath City: 140,000 and Oceanport: 50,000)

Rivertown has about 40,000 people and has most of the buisness of the Metro.

     Rivertown started out as a trading post out on a road leading into Grath City. (Ironic name there's no river anywhere in the region)

When Grath City grew so did Rivertown. It's lack of sanitation is steadily declining the population. 

HIGHLAND:

Highland started just as small settlement made by the farmers who needed more land for crops. Now the city has about 11,000 people and is a major buisness center just of Interprovince 2 (highway) south of Rivertown.

SHORE CITY:

Shore City is a laid back little town of just over 7,000 on the Intrani Ocean on the east of the peninsula. It is directly south of the bustling Grath City but still keeps itself as a peacful place. (mostly from the heavy traffic in Rivertown)
