This Rotter was gifted by Pestial, who is one of the seven Proctors of Pestilence and he ensures that plagues reach their respective destination. However, Pestial is a devious and lazy proctor who merely ensure that something of nurgle's (whether it be the plague itself, a group of nurglings, or whatnot) reaches some destination. As such, Nurgle is slightly annoyed by the laziness of Pestial, but is content that someone recieves his gift one way or another.
