Just as many yamarajes become fascinated with souls possessing specific experiences or from certain backgrounds, some of the psychopomps go out of their way to judge beings from specific worlds, collecting bits of information and insight with every creature that passes them by. Thus, some become experts on one or multiple worlds, having spent eternities ferreting out the histories and secrets of worlds from firsthand accounts over millennia of inquiries. Many yamarajes welcome the opportunity to share the details of their investigations, though they sometimes see inquiries into their worlds of expertise as opportunities to conscript new allies to aid the psychopomps' cause. Standing at the pinnacle of their race, yamarajes are well informed as to the challenges and goals of many subservient psychopomps, and might only negotiate with mortals who perform a service in aid of their underlings.
