The Death of Rats
Reaper
!
For anybody not familiar, Terry Pratchett's Discworld series features Death as a character pretty frequently. He deals with the tedious work of making sure dead people are dead and the like, at least for everything but rats. Rats are covered by his counterpart(?) the Death of Rats, also known as the Grim Squeaker, mostly because so many rodents die so quickly, he couldn't be bothered with managing all of them.
Now that we have 2 or 3 reaper/soul-collector champs, why not lighten their load by having
take over for the collection of his rodenty brethren?
