There are 14 kingdoms; 7 led by benevolence and 7 led by malevolence - a seven deadly sins theme. Thus, the emergence of two confederacies, one in the pursuit of peace, in respect to the Vessels of Virtue, and the other in pursuit of corruption, in respect to the Sinister Seven. After defeating the despots of Sinister, you will be able to liberate the oppressed Pokemon and residence of the kingdom. However, you will not be able to bypass the kingdom walls; you will only be able to do so once you have proven your ability to a Virtue Fighter that presides over the tranquil and liberated kingdoms and obtaining a hidden move.
The 3 types not covered by the rulers will be grass, fire, and water. These will be represented by the 3 main antagonists. These antagonists break into the beginning kingdom just before you select your starter Pokemon. You will then be given a rare Pokemon in an act of desperation; it will have the ability to transform into either grass, fire, or water.
Just in! The Shichi region is reverting back to that nostalgic aesthetic we all fell in love with in Pokemon Gold/Silver/Crystal!
