"He who fights against monsters should see to it that he does not become a monster in the process."
     —Friedrich Nietzsche

• A wizard in the process of developing magically sentient "alchemice" enters his lab one morning to find the cage doors opened, the locks apparently picked by the small bits of wire left lying on the workbench. A large number of potions are missing, and the cat is sealed into a half-full bottle of formaldehyde. His life becomes a nightmare.
• Packs of reptilian bonethieves lurk in the depths of primal rain forests, magically absorbing the bones of living prey to stimulate the growth of their own protective bony horns and plating.
• A candle golem is spontaneously created when the wax from mundane candles used in a wizard's library is gathered, melted down, and reused one too many times. The loose arcane energy absorbed by the wax gives this tiny being a free will and an erratic response to magic.
• A party of adventurers, bloody and without magic following an epic battle with a dragon, is driven away from the site of their victory by dracoticks vacating the corpse of their dragon host. Suffused with the dragon's blood and camouflaged to look like its scales, the dracoticks unleash potent breath weapons that make for a dangerous treasure hunt.
