Belator is just a chill guy, even before he met Raloud it seems. He clearly had doubts about his job by this point, and Raloud seems to be what got through to him. I want to know why Belator became a Bureau officer in the first place. He clearly places helping people above killing mages...
Also, why does Gheer have beef with Raloud now? Since there's no possible reason so far, I assume he will reappear later, possibly after a run-in with Quovelta. He must have gotten that earth-bending magic tool from somewhere, and he isn't connected to the Bureau... I have many questions, but not enough information to speculate on.
