What errands could you possibly run for Death…?
Well there was that time He asked you to fetch Him a sandwich from the deli in Revenich. Of course He didn’t tell you that the chef would try to cut off your hands with a meat cleaver if you took the sandwich out of his restaurant. Then He asked you to give the sandwich to a Formian queen. The colony captured you and the queen ate the sandwich as spoils of conquest. Turns out that it was poisoned, so she died and the entire colony had to commit suicide. You survived the encounter surrounded by thousands of human-sized ant corpses, which was disgusting but made the river Styx easy to find again.
Then there was the time He asked you to buy an outfit from the finest dressmaker in Sigil… Well that went really smoothly actually, but He didn’t tell you what He did with the dress. Maybe He’s wearing it under that big black robe right now. Probably best not to ask…
