That looks magnificent!
I wonder if this is where the Zombies, Skeletons and Creepers come from? Could be a pretty interesting mechanic if you could only go there safely at night (when the monsters are invading in the real world) and if you try to enter during the day, you quickly get overwhelmed and murdered.
As the sun rises in the "good" world, and the monsters' bodies self-destruct, their dark souls should reappear in the Hell dimension.
Also, maybe if you spend too long there you become a zombie yourself, and if you return to the real world without curing yourself, daylight sets you on fire?
Loads of possibilities!
