Reaper

A mix of the Runner and the Taker. Someone who, often on commission or in response to a karmic duty, will confiscate the power or resources of an offending party who has intentionally evaded them. Repossession is the best possible real-world comparison.

The Grim Reaper could be said to have a duty to take the Time or the life-force of the soon-to-be-deceased from them, to prevent them from abusing it. This, however, would make them definitively incompatible with the role of a psychopomp, who transports souls, and would therefore be referred to as a Soul Courier. A Reaper would more accurately be the person who collects the evasive resource (or offender) before handing it (or them) off to the Courier.
