The cave itself because it is not trodden by human presence, slowly created its own ecosystem.
For some weird reason, plans inside this cave grows exceedingly fast and the fruits it produced is very good in helping people to get full.
Azief think it has to do with the energy he brought with him when he is falling from the Supremacy Stairway.
There is even a lake in this cave.
Azief notices that when there is rain outside the water would flow inside this cave but it used to flow back through the hole and disappeared into the ground or some other gaps
He was bored all day living in this empty dark cave.
He wanted to at least make it a little bit beautiful. At times like this he is reminded of Katarina and smiles bitterly. She was always the artistic one.
And she always like things to be beautiful.
Azief uses his palm smash to create a hole and since then a lake was formed inside this cave. It is pleasant to look at.
