Obsidian wall

Consists of	Obsidian
Can generate in existing chunks	No

The obsidian wall was an experimental, short-lived debugging structure made up exclusively of obsidian.

Generation[]

Obsidian walls would generate on the uppermost blocks which had an X or Z coordinate of 0. This formed a set of two walls, for the two cardinal directions, intersecting at the center of the world.

Structure[]

The player would spawn at the point of intersection of the two resulting planes. The wall was always made of 2 block high obsidian which was placed on top of existing terrain. From there, it would generate obsidian going all the way down to the bottom of the world replacing any stone, dirt, or grass blocks below it.
