The Ferrum
Explore a new dimension called the Ferrum, a desert world with an abundance of iron, coal and ancient tombs. Beware of the pyramids, however, as they are guarded by a mysterious force that does not welcome you to it's domain.
This mod adds the following:
-The Ferrum, a desert dimension with 3 distinct biomes
-4 structures
-3 mobs
-2 ores (+ new variants of iron and coal ore)
-2 food items
-A farmable plant
-A powerful fuel source
-A new boss
Accessing the Ferrum
To create the portal igniter you need 2 iron ingots and a redstone torch. In a crafting table, place the ingots in a vertical line and top it with the redstone torch. This will create a Redstone Screwdriver.
Then, create a 4x5 (2x3 without the corners) portal frame out of iron blocks (like you would with obsidian to make a Nether portal). Right click the inside of the frame with the Redstone Screwdriver to ignite it.
