User blog:The Mind Player II/What exactly are Reapers?

We know they are not angels, at least not the same type of angels as Heaven's angels, and they act as mini-Deaths. They are weak and vulnerable to Angels blades, and mostly the same things as angels, even the closing of Heaven, but they answer Death and not God....

My question is, are they angels, but created by death, for Death, similarly to God's angels?
