About 2000 years ago there was world which was divided into three realms. One was human realm; one was demon realm, and the third was the immortal realm. In immortal realm the affairs of whole of the human world were looked after by LORD OF FATE: VASHIST. Immortal realm contained three superior deities who would control all of the immortals in there. They were LADY MARIA, LADY NERSAL and LORD SARAS. Lady Maria was extremely beautiful, dominant and proud deity, Lady Nersal was calm and fun-loving deity, and Lord Saras was younger among the three deities. His father was the previous superior deity and was died few years back in war of immortals and demons. So as the one and only heir of the family he was chosen for the position of superior deity, but the whole affairs were looked after by other two deities.
After the war which happened between immortals and demons years back immortal clan had eradicated the whole demon clan. Few of the demon clan who belong to polar fox clan had reincarnated as human beings in mortal realm. The leader of polar fox clan was MERSA. Polar fox clan members were strongest and powerful and the demons, but none of the immortals know the exact location of them in the mortal realm. They themselves remember nothing of their previous lives and once they remember their past, they will gain all the powers not only of their clan but also of the whole demon realm.
