Consider Death

In the end, Sunny lost more than he gained from his first venture into the Shadow Realm. 

He had gained precious knowledge of what awaited him on the other side of the Gates of Shadow… as well as two black arrows, one smeared in his own blood. 

After retrieving the second arrow from the ceiling of the dining hall of the Brilliant Emporium, Sunny studied them both with a dark expression. 

The arrows were not enchanted in any way. In fact, they looked quite simple, almost makeshift — the shafts were made of dark wood, the arrowheads were cut from obsidian, and the fletching was made from crow feathers. Nevertheless, there was nothing mundane about them.
