Fair Folk like to boast about being immortal, but they do not live forever, and they can be slain by violence. Fair Folk also eventually grow old, though it takes a very long time for most with most of them having life spans between 250 and 2500 years old. Technically they do not "die" of old age, but they do cease to be. During a Fae's "twilight time" a Fair Folk will lose his or her mental faculties while physically mutating, transition from one of the Fair Folk into that of a Remnant. Remnants take many forms, plant, beast, or even a landmark. Remnants are often extremely strange, such as a perpetually flaming willow tree that is always making crying noises. Whatever form they take, Remnants have a symbolic connection to the Fair Folk they once was. Some Remnants are dangerous, some are beneficent, and many are merely benign oddities neither harmful nor helpful. Monogamous Faerie couples often go into their twilight together and merge into a single dualistic Remnants. Likewise, twins are very common among the Fair Folk become merged Remnants when they die. Some Fair Folk are comforted by the notion that a part of them will always live on, but others view the mental and physical mutations as terrifying. Fair Folk are a proud people, very few Fae will admit they fear becoming Remnants. Certain Remnants are considered blessed and some are considered cursed, and the Fair Folk have many superstitions about what actions in life lead one into becoming a pleasant reincarnation or a foul one.
