Calumny

Calumny is a Druid the time of Ultima IV who can be found in Yew.

He is a weaver of magic who imparts to The Stranger the combination of reagents for the Quickness spell -- an enchantment which he created. As inventor of the spell, he also knew where to locate its most critical reagent: Mandrake Root.

Trivia

 * Calumny is one of several NPCs in Ultima IV who inform the player that any spell that calls for more than a single portion of a reagent actually requires only ONE portion of that reagent. Perhaps this was the designers' way of getting around a limitation of the game engine after The Book of Mystic Wisdom had already been printed?
