(This is just an idea)
The Crystal of Destructions version of the Realm of Creation...
It's a seemingly endless cavern, filled with ravines and acidic liquid dripping from the ceiling...
The deeper you go, the stranger it gets, the stalactites and stalagmites are suddenly everywhere and twisted... eventually, the person going through will experience hallucinations, sometimes they will hear the voice of a loved one, other times they may see a loved one.
After a few hours, the Destructites will appear. The Destructites are distorted creatures made from pure Destruction that can mimic voices or take certain appearances to lure in their prey. Once caught, they will tear apart the prey into pieces they can eat. Once all of the meat has been eaten, they scatter the skeletal remains.
The Destructites are very fast, strong, and hungry. There is very little chance of surviving an attack by one. Your only hope is another Destructite showing up, for the Destructites will fight over their prey. You can use this chance to slip away.
There is no known escape, besides using the Crystal of Destruction to open a portal out.
