History
On the day Jahad declared himself the King of the Tower he decided to stop climbing, thus hiding the key that will open the door leading to the higher Floors so that no one could go over the 134F.

Apparently, Jahad divided the key into two parts. He gave the first half of the key to the blacksmith Ashul Edwaru. Ashul melted half of the key and turned them into 13 weapons, which he made the princesses fight over them. The other half of the key was melt into several crimson rings displaying the crest of Jahad. These rings were handed to children who inherited the blood of Jahad, whose existence was meant to be kept hidden alongside the rings.

It is said that when all of the princes of Jahad are able to climb the Tower, the door of the Tower will open one again. Because of this, many speculate who is the real prince of Jahad that will take the Tower’s last test.
