Another factor that made the Gundam Shelter unique was the 3 forests which grew as they absorbed mystic energy and later evolved into Great Forests.
Rex and his companions already experienced the Great Forest of Elias. As for the Great Ape Forest, it was home to the incredible Apes.
These incredible Apes were some that benefited most from the advent of mystic energy. They mutated, not just gaining more strength, but also gaining more intelligence that literally put them on the same level as some humans.
The strongest Apes of the Great Ape Forest could ride Hell Horses, they could use mystic weapons, they were some of the real dangers to humanity.
Despite the danger of the Great Ape Forest though, it was nowhere as dangerous as its last counterpart, the Great Dungeon Forest.
The Great Dungeon Forest was ranked in the world as the 3rd in the list of the 5 most mystical locations that appeared after the age of awakening.
