Hell in Dungeon Fantasy

[Jovus]

Actually, souls, or spirits, being simply a form of rareified matter, are subject to Gay-Lussac's law, and so if we assume a constant volume of Hell, it becomes quite easily a very efficient heat engine. This explains both how energy is extracted from Hell and why, even to the uneducated mind, it is understood to be very hot. Thus the explanation of why souls go to Hell rests on the understanding of why this energy is needed.
