King's Savior

King's Savior is a plant that appears ONLY in  Ultima VII Part Two.

Description
Green with spiked foliage and tiny yellow blossoms, King's Savior can be found growing near mushrooms on the western shore of Serpent Isle's Great Northern Forest. A powerful sleep arrow can be created by treating an ordinary projectile with the plant, inducing an instant, deep slumber in the target stricken by it.

Whilst in pursuit of the fugitive sage Batlin, the Avatar used this method to incapacitate the tyrannical and seemingly invulnerable Draygan in his despotic mining camp, that the source of his power—the mystical Orb of Elerion—might be rightfully returned to the Forest Master, Morghrim, and the enslaved Beryl liberated from her servitude.

Trivia

 * King's Savior may be a pastiche of King's Foil, a plant that had healing properties in J. R. R. Tolkien's The Lord of the Rings.
