The Hidden Ruins is a place hidden in the map of Minecraftia. It is a foggy stone valley and in the middle rests a volcano. In the volcano is an obsidian deposit which covers an empty magma chamber, used as Herobrine's jail until Endarkness rescued him. In this place, it rains lava and snows obsidian. It is a very dangerous place. On the volcano, there is an Ender Crystal, used to keep seals, which can later on be used for different tasks.
