This is an article about The Hidden Emerald Dimension, a location created by Rosie the Echidna.

Overview of Area   

The Hidden Emerald Dimension is a mysterious subworld of pure energy, deep within Mobius, which provides the planet with energy, allowing the Power Rings and Chaos Emeralds to exist.  Legend dictates that it was created by an omnipotent jade Chinese dragon called the Elder Dragon, who filled an empty void, within Mobius, with a special power, giving birth to the dimension and filling it and the rest of the planet with great power.  However, the appearance of the dimension is different to that of the rest of the world.  The colors of the sky and grass are inverted and almost every aspect of the area can fill one with energy.  Even the tree leaves, which are plump and edible, can rehydrate and energize someone.  This eventually resulted in the birth of a unique group of organisms, within the dimension, called HED Mobians.  

Consequently, Mobians who somehow enter this modified void, most likely from the aid of a HED Being, can feel their bodies being altered by the mysterious energy, making them more like a HED Mobian themselves.  


The entire dimension live under a culture in which all individuals take part in training under at least one style of martial arts, resulting in almost all HED Beings becoming warriors and fighters.  Nearly all of their customs revolve around martial arts, from forging friendships to marriage, etc.  More importantly, HED Mobians usually work to achieve their True Potential, in order grow as warriors and as Mobians. The most respected HED Mobians are usually the strongest and most skilled martial artists whose power is known to the public through spectated sparring matches.

Forest Terriorty

The is section lies at the center of the Hidden Emerald Dimension and is home to the world's most skilled martial artists and many ninja and warrior tribes.  It is a colossal taiga, composed of three different forest areas.  It holds the biggest amount and variety of trees and is also the resting place of the Elder Emerald, the dimension's most noticeable relic of the Elder Dragon.  The Forest Territory is usually the main place for HED Mobians to go for advanced martial arts training and fighting tournaments.

Crystal Haven
