Not to be confused with Death
Death is an entity widely regarded as the personification of death.
According to Russian folklore, Death was among a hellish horde released by Vigo to end a war in Russia. The Undying Soldier used his Mystical Sack to trap Death. The soldier was invincible and drove back the rest of the horde. However, as the soldier lived on, he became terribly ill. The soldier asked Death to take him to the next life when he released it. Death refused and cursed him for trapping him. The soldier wandered the earth ever sick and unable to die.
Sometime in the 1970s, Death appeared to Eugene Visitor after he was hit by a car. Eugene recalled a paper he wrote on Russian folklore and ordered Death into his bag. Death complied and Eugene vanished without a trace. Eugene reappeared 20 years later where Egon Spengler was dealing with a sustained spike in the ambient psychokinetic energy field. Egon believed the absence of the entity was the source of the extra spiritual energy. If Death was not released, Egon believed it would have a catastrophic effect on the physical plane... a breach between Earth and the Other Side. Eugene refused to release Death and demanded concrete proof first before even considering it.
In November, the Megaspook event convinced Eugene to release Death. It sensed the Megaspook and teleported straight to Herald Square. As the Megaspook cowered, Death simply stated, "Mine" and rammed into the ghost. A flash of white light enveloped the area. Death and the Megaspook were gone. Not one to hold a grudge, Death allowed Eugene to say goodbye to Egon before he was dispersed. With Death free, Egon predicted ambient P.K.E. levels would return to normal levels shortly.
Egon believes Death has the power to siphon excess P.K.E. from this dimensional plane. Death had to power to disperse even the Megaspook with one blow and demonstrated the power to travel vast distances in seconds, teleporting from Belleville, New Jersey to Herald Square, New York within seconds.
Tristan Jones initially planned on exploring more of the science behind Death and the sack but ran out of pages. Jones notes he views Death as a "particularly nasty kind of spirit. Something akin to the Dementors in Harry Potter" and has an idea to expand on psychopomp creatures.  Some beliefs posit Death as merely a psychopomp who functions only to sever the last ties between the soul and the body and to guide the deceased to the next world. He has no control over the victim's death.
