The darklands

The darklands would be a late game dimension only found after defeating the ender dragon. It would have a red version of the nether portal texture and it would be made with twelve endorite blocks (see my other post) in the shape of the end portal. It would be lit by placing redstone dust on top of each endorite block, and seting the midle block of the portal on fire. Once inside the darklands you find that it is pitch black. as long as you're in there you have a version of the effect blindness but you can see ten blocks ahead instead of two. You can come across pitch black phantoms with peircing red eyes and they deal bouble the damage of a normal phantom. You will also find redstone and quartz. The ground is made of basalt and patches of black sand. There are streams of red lava that can even penetrate the blindness but twice as deadly. You could also find all the mobs from the prison labrynth in minecraft story mode. like the spider-creepers and red and black zombies. It would also have a ceiling like the nether but made of basalt. You can bottle the red lava and use it in potions, similar to dragon's breath. It would make any single potion into three.
