The Forge is a location first seen in the episode "Bismuth". It is the forge where all of the Crystal Gems' material weapons for the Rebellion were made. All of the weapons were made by Bismuth, including Rose Quartz's sword. It also houses upgrades for the weapons, which remain even after being dematerialized.
General Location and EntranceThe Forge is located inside an active volcano in an unknown location. The entrance to the Forge can only be opened by Bismuth. It resembles her gemstone when opened.
Main LevelThe main level of the Forge consists of a stone room. By activating a stone column, lava can be streamed through the walls and into the room. There are three barrels of dust, an anvil in the middle of the room, weapons hanging everywhere, a blue chest with Gem weapon enhancements inside, and a keyhole only usable by Bismuth to go to the basement level.
Basement LevelThe basement of the Forge consists of a hexagon shaped floor that descends from the main level. It is surrounded by matching tiles with rock molds to make training dummy Gems. This is also where the Breaking Point is introduced and where Steven and Bismuth battled.
- The location of the Forge may be a reference to the Greek god Hephaestus, whose forge is also located inside a volcano.
