Baby's first mod. Adds black iron as a mineable metal. Why? Because I felt like it. Slightly stronger than steel and better at heat insulation, but also less common. You can build weapons, armour, and buildings out of it, but it is not a complete replacement for steel. Enjoy. Or don't. I don't care.
Post suggestions for improvement and balancing here, but please be aware that my knowledge of modding is very limited.
