Hephestus is my content contribution to Olympia. It is what is responsible for all 70k+ blocks and items. It hooks into Olympia the same exact what that other addons will. Included in Hephestus is 49 flavours of metal, 32 flavours of stone, 69 flavours of wood, and lots more. This requires Olympia Core. I only included it seperately from the Complete is just in case you want to try out Hephestus later.
