Pledge

About
Just North of Vacuo and West of Vale is a cluster of small cities that are holding on for dear life, in the nation of Pledge. Having no natural barriers, they are constantly bombarded by Grimm attacks, as well as other natural disasters. Even though all odds are stacked against this nation, it continues to exist.

Pledge is governed by Vacuo, and is set up as an extra resources nation. There is no in-house Training Institute for Huntsman, so young people normally move to Vale or Vacuo to pursue the life of a Hunter.

Verge
The main city and bustling metropolis, Verge, was the first established stronghold in Pledge. A sky-high wall surrounds its borders, as well as a Dust force-field locking the city in a dome, save for the few ports the city has. It's stood strong for the past 100 years, and doesn't seem to be going anywhere soon.

Ardent
Just west of Verge, closer to the forest, is a major seaport city, filtering most of the resources coming into the main city. Ardent also possesses a wall and a dome made from Dust much like its counterpart, and the two cities have developed quite a symbiotic relationship

Verdant Forest
Just to the south of Pledge, closer to the coast, is an extremely luscious, temperate forest. Many Grimm are housed here, but this is where Pledge gets the plethora of resources needed to build up its cities. Lots of the Kingdom's Hunters like to come here to practice combat, as well as help clear out the Grimm population.
