Long ago, Ido Front was used as a ritual site by the ancient people that inhabited the Abyss. It has since been transformed by Bondrewd into his main base of operations. Here he conducts experiments in warding the curse.
It was here that Bondrewd brought Nanachi, Mitty, and other children to act as his test subjects, and where Nanachi and Mitty transformed into narehate after ascending from the Miniature Garden of Dawn. It is also the place where Bondrewd raised Prushka as his adopted daughter before turning her into a cartridge, then into a Life Reverberating Stone.
- Based on a comment from Majikajya saying that Nanachi is a narehate of the "old ritual site," it is possible that the rituals that took place at Ido Front long ago involved an individual receiving the blessing. How the blessing was achieved by the ancient people is unknown.
