Rasatala was the realm of various kinds of supernatural beings.
Ghouls, ghosts, monsters, divine nymphs, and various kinds of magical creatures lived inside this vast and collosal realm.
The Ichadhari Nagas were deemed to be the most superior race. They were masters of countless powers. It is said that these Nagas have the same intelligence and emotional capacity as humans.
In reality, none of the creatures dwelling in this realm had ever seen an actual human being.
All of the things they knew about humans were thousands of years old. The facts were dated when humans and magical creatures could still live together.
The magical world was the polar opposite of the human world. The inhabitants of Rasatala didn't know how humans lived, what they ate, or how they traveled. Everything about humans was a mystery to them.
It's common knowledge that people tend to make stories about the things that are mysterious and unknown to them.
