"Precisely. He had slain a number of his neighbors' pets for some vague ritual in an attempt to replicate that of Grayhallow. He was aware of the moral reprehensibility of his actions, inclusive of the collection of the pets' blood and bodies, but that did not stop him. He attempted to summon an armada of demonic legions to annihilate or enslave all life, but was terrified into insanity by the visions of the creatures' habitats. In the end, his wife walked in on him mid-casting, and he panicked. Zathog proceeded to slice her into approximately thirty-two pieces, which he sold to his neighbors as overpriced sausages. Strangely, he abandoned his business with pet-sacrificing, and proceeded to continue with the sausage business. It was abnormally lucrative. The authorities eventually grew wise to his expedients, however. They stormed his house. Zathog had prepared for their arrival, and killed each of the constables. After a while without return, the citizens grew uneasy, and sent people in search of them. A handful of citizens searched Zathog's residence, and found him sitting in the middle of the floor, surrounded in a circle of bodies. It was too late for them to have done anything, and Zathog had carved detonation runes into his body, and into those of the authorities. Many were lost in the explosion. His body was locked in a discrete location by some occultists, and has not been seen since, fortunately. His method became the inspiration for several suicide bombings with those precise runes at occasional political events. Fortunately, they are rare."
