During his travels in remote and fantastic lands, Lemuel Gulliver encountered a country in which, occasionally, a child is born with a red circular mark over his left eyebrow. This mark, which darkens and grows to the size of a shilling as the child ages, is a sign of immortality. This immortality is not hereditary and these immortals do not enjoy perpetual youth. Instead, they stop aging after about 80 years, after which time their society considers them dead. Once an immortal is declared dead, his heirs inherit his property and he must live on the public dole. Because the language of their country changes so frequently, immortals eventually become incapable of conversing with their countrymen and are regarded as foreigners in their homeland. Name these unfortunate souls and their fictional country.
