Therajomas Kanze
Therajomas Kanze was a Historian[1a] who was a founding member of the Order of Interrogation, that Kyril Sindermann formed during the Horus Heresy's Battle for Terra.[1b]
History
They were tasked with recording the history of the Battle for Terra, even as it still raged, and were given permission to go where they wanted. However the Primarch Dorn would not allow Sindermann to have this choice. Instead the Primarch would tell Sindermann where to go, though, Dorn would allow other Interrogators to accompany him. Sindermann's first mission was to visit the Bhab Bastion and he first thought to ask Hari Harr to travel with him. However after seeing that Harr was intent on going his own way, Sindermann asked Kanze instead.[1b]
