The Middle Ages were, considered by many, to be the bloodiest time in history. Famine, war and generaluncleanliness caused witches and wizards of the time to be prone to dangerous downward mood swings. Foultemperament paired with a wand held disastrous consequences. Setting off an angry party could be as simpleas accidentally running into them at the market, or angering your neighbor by playing too loudly of a jig. If lucky, the injured party could escape with something as simple as receiving a curse causing an itch inunmentionable places but more probable was mortal danger. In bad times it was hard to trust even a good person. A favorite aunt, for example, could be likely to use an unforgivable curse if pestered by fleas or asmelly house guest.Witches and wizards of the age found it therefore necessary to conjure a way to identify these ill wishers. Asimple charm was devised that, when produced correctly, would warn of danger within the intended area. Thischarm was known as Inimicus Reperio, the foe finder. The Latin texts for conjuring this charm reads:Sub a plenus luna , cruor moss quod oculus of newt erant promiscuus in unda haud magis quod haud minor quam 77 inhonestus. A incendia tunc exsisto lit sub lebes quod quondam is coepi ferveo a planta of alveuswould exsisto added. quod vel veneficus tunc chant lepor lepos Inimicus ut quinque vicis , insquequo liquidusvolvit a splendens umbra of argentum.Under a full moon, blood moss would be mixed in water no more and no less than 77 degrees. Then, after chanting Inimicus The witch or wizard should then chant the charm Inimicus three to five times, until theliquid turned a dull gray. A sprig of holly would then be added and the gray would then be added. If all wasdone correctly, the liquid would become a brilliant shade of silver.The charmed liquid would then be poured into a vase or jar and usually kept beside the main entrance of thewitch or wizard's home. When danger was not present the liquid would remain it's silver shade, but if an ill-intending wizard were to enter the property the liquid would immediately turn a bright shade of red and beginto whistle. Therefore, the wizard or witch would be able to defend him or her herself before the villainousguest could speak his/her first spell or wiggle his/her wand.However, if not brewed correctly the charm was known to become too “touchy.” Rather than only indicatingwitches and wizards who intended to cause harm, a badly produced charm would indicate those who were justin grumpy moods. This would add to accidents, such as a brother or a cousin being hexed simply because he'd been dumped by his fair maiden.While useful during it's time, Inimicus Reperio was eventually replaced with simpler items such as Foe Glassand Sneakoscopes. These items not only accomplish the same feat with less effort are known to be less proneto accident. Still, when entering the home of an elderly witch or wizard it is not uncommon to notice a vase, of brilliant silver liquid at each entry
