This dungeon is partially based off the Chaos Altar maze in Runescape. Players must transverse through this pitch black maze of puzzles to reach the Diamond Ore Tree at the end. Beware though, a fatal misstep can send you plummeting into the void.

This is located deep underground touching the void. Although it is hard to see it in the picture, it is surrounded by Bedrock although players without fly would be incapable of seeing it making it seem like endless space.
The entrance is at the center of the dungeon marked by a nether portal while the trees are located at the far north and south sides. As of now, only the north side of the dungeon is complete.

World Edit is used to dig out the 120x120x20 area. The rest is done with TMI and the //up command. Flymod is necessary to construct this too. This is made in Survival Single Player.
