Dragon Forge

The Dragon Forge is used to make powerful weapons and tools. There are 3 types of forges, although only 1 is currently available. The Aether Forge is the only forge currently usable. The other 2 types are the Draconic Forge, and the Hellstone forge. The forge uses materials often found in dungeons. This is considered "end game" content and it is suggested that you complete vanilla survival before diving into the forge. The forge can be traveled to with /warp forge. It is also connected to the white bridge that connects to the shops, court, and PVP arena. 

Other information on the forge can be found in the Dragon Forge book.
