The Iron Dimension is a dimension added by MoreDimensions.
Entering and Exiting the Iron Dimension
Entering the Iron Dimension is similar to entering The Nether. However, instead of using Obsidian, Blocks of Iron are used. Additionally, the portal is activated with an Iron Igniter rather than Flint and Steel.
Similar to The Nether, when entering the Iron Dimension another portal is auto-generated within the new dimension.
The Iron Portal makes noise like the Nether Portal.
Like The Overworld, the Iron Dimension has a sequence of day and night, but without rain.
There are no mobs implemented in the Iron Dimension yet.
