Gimble

Gimble is a sick man living in Minoc's Poor House during Ultima IV.

Description
Barely conscious and deeply ill, Gimble would reveal to the Stranger that he had suffered the bite of a tstse fly and that he soon expected to die from the resulting sickness. Should the hero be kind enough to spare some alms for the dying man, he would reveal that the carver, Azure, knew of the Rune of Sacrifice.

Trivia

 * The illness most associated with tsetse bites is African trypanosomiasis or "sleeping sickness," a parasitic disease caused by  trypanosoma brucei protozoa transmitted by infected flies. Gimble appears to have symptoms consistent of the neurological phase of this illness, which is marked by disruptions of the sleep cycle.
 * In the Nintendo port of Ultima IV, a nameless man suffering from sleeping sickness may be found in the Minoxian Poor House. Should the Stranger agree to buy him a drink, he will reveal the location of  Rune of Sacrifice.
