Nimueh's Chalice

Nimueh's chalice was a goblet used by the sorceress Nimueh in an attempted assassination of the warlock Merlin.

Prior to the signing of a peace treaty between Lord Bayard of Mercia and King Uther of Camelot, Nimueh poisoned the chalice with a petal of the Mortaeus flower enhanced with an enchment to quicken the progression of the poisoning. She then posed as a servant girl in Bayard's entourage named Cara in order to trade the poisoned goblet with one of a pair meant as gifts for Uther and Prince Arthur during the feast following the signing of the treaty. Nimueh replaced the goblet meant for Arthur, and secretly told Merlin that Bayard had poisoned the chalice in an attempt to kill Arthur. Merlin stopped Arthur from drinking from the goblet and accused Bayard of poisoning it, prompting Uther to instruct Merlin to drink from the goblet himself in order to prove his assertion.

Merlin did so and quickly collapsed from the effects of the poison.
