Star Core

The Forge, an artificial world created by Draught for making weapons and equipment. Inside this world, there is an unending sea of molten liquid lava flowing. 

Despite the endless molten lava everywhere, the environment is still safe for ordinary people to breathe. As long as people could withstand the heat, ordinary people could live inside this artificial world.

Still, Unlike the real world, the Forge didn't have a sky. Once people look up, all they see is nothing but darkness. On the horizon, there is also nothing but darkness. The only source of light is the molten lava sea.

Getting out from the cave, Draught waves his hand, and a platform made of stone appears in front of him from the molten lava sea. *GRRTT*

"Come, follow me." said Draught as we walked toward the platform that kept appearing from the lava sea, making a sort of bridge.
