Dark souls

Rumors a new biome called The Fire Biome are popping up for 1.7. What would be in the fire biome? Maybe a new mob called Dark souls.

Section heading
Dark Souls would explore around the fire biome and would usually attack the player on sight. They look like a blaze except blacker and more like a ender men. They would be very powerful and send weaker fire balls that are like the Ghast. These fire balls can be used in a potion for Blaze potion which can set people on fire.

Dark Souls would be a very good idea for the biome but other mobs would be required. Maybe the Red Dragon would appear in the fire biomes for they are said to be added in 1.7.
