Umbra Hands

The Praying Hands is the name of Bondrewd's group. It can be assumed that all members of the Praying Hands are people that that Bondrewd has spread his consciousness to, as Bondrewd tells Nanachi "Every single one the Praying Hands is but myself". It is mentioned that all of them are Black Whistles. They carry out most of Bondrewd's work for him. Most of them are located at Idofront, as it is harder for Bondrewd to control them across layers. This doesn't mean all of them are at Idofront, however.
