Generate a ruined Nether portal structure in Minecraft, not a voxel statue. Build it as a normal Minecraft structure made from standard blocks like obsidian, crying obsidian, netherrack, magma blocks and blackstone. The portal frame should be partially destroyed with missing corners and broken obsidian pieces. Around the portal place fire, lava pools and scattered blocks to make it look dangerous and aggressive. The structure should look natural, like a ruined portal that generated in the world, not like a statue or pixel sculpture. Keep the build realistic for Minecraft survival mode.Do NOT generate voxel sculptures or statues. Generate a natural Minecraft structure.
