Long time ago, the 2nd Floor is used to conduct simple Tests like any other, but after the intrusion of certain Irregulars such as Urek Mazino and Phantaminum caused the incumbents of the Zahard Empire to feel insecure. In order to maintain their seat of power, the Zahard Empire then placed this classified High Ranker from one of the 10 Great Families as the Ruler and made this floor to function as an outpost where the Ruler in charge will watch and sort out any "dangerous individuals", and if possible eliminate them out before they could grow to become a real threat to the Tower.[2] After Evankhell killed the Ruler from Zahard Empire, she took the ownership of this floor as its new Ruler.[1] Evidence of this can be seen on the symbol which still remains on the corner of the Evankhell's Mothership.
