This is a pre-made structure with a fairly expensive recipe for an interesting gate to the nether.

While a normal nether portal is cheaper to make than this one, this structure adds some character to the portal and makes a large gate as well.

The item configuration is very straightforward and can be seen below.

The recipe for this item is fairly expensive and should be obtainable late in the game. You will need the following:

• 4 - Obsidian Blocks
• 4 - Double Compressed Stone
• 1 - Flint and Steel
