Unholy Energy represents the power of corruption, diametrically opposed to Holy Energy. Items imbued with unholy energy often deteriorate over time if not enchanted - metal becomes brittle, stone fragile, and once living tissue susceptible to reanimation as undead or the creation of flesh golems upon death.
Those with an understanding of energy composition will inform you that the individuals who led an immoral life, tainted by their profane energy, make ideal candidates for a dark resurrection, a vessel for negative energy, an undead.
Spells and abilities imbued with the Evil descriptor draw upon Unholy Energy.
