Calumny

Calumny is a druid at 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.
