The top of the volcanic mountain, it is near impossible for any normal person or creature to see very far down inside of the volcanic mountain. The heat alone that is emitted would stop most from being able to stand looking inside without sustaining burns or at least have trouble breathing from the smoke and lack of oxygen as it is rapidly burnt away. The fire emitted will set just about anything flammable alight very easily as the black and other dark coloured flames will engulf and devour just about everything it touches and shall not be put out as though normal fire due to the magical nature to it.
