No need to worry, anonymous! It’s merely a myth that litwick need large sources of life force to survive. Very likely, your litwick is simply feeding on the smaller insects, mites, and other vermin that may be inhabiting your home. Perhaps also your houseplants.
Bill, I’m not sure this is at all reassuring… —LH
Litwick
The Candle Pokémon
Type: Ghost/Fire
Official Registration #: 607
Entry: Litwick are known for two things. First, they exclusively inhabit old mansions and other stately buildings. Second, they feed on the life force of those who mistake its cute smile, its candle-like appearance, and its eagerness to help for an actual attempt to lead lost travelers to safety. Due to both of these facts at once, litwick encounters are among the highest causes of death for anyone who has seen the film Beauty and the Beast in recent years.
Lampent
The Lamp Pokémon
Type: Ghost/Fire
Official Registration #: 608
Entry: The evolved form of litwick, by battle experience. More benevolent compared to the other members of its evolutionary line, lampent do not prey on the living but rather wander the streets of populated areas and feed on the dead. For this reason, lampent are popular to keep within the house as wards against evil spirits, but it should be kept in mind that this also means that lampent are rather tasteless gifts for the elderly. (For this reason, lampent are extremely popular gifts for the elderly in their home region of Unova.)
Chandelure
The Luring Pokémon
Type: Ghost/Fire
Official Registration #: 609
Entry: The evolved form of lampent, by exposure to dusk stone. While not necessarily any more docile or benevolent than its previous forms, chandelure are not known for actively hunting down prey. Instead, they lures prey into their flames by maneuvering their arms in hypnotic loops, and once prey is ensnared, chandelure passively allow their fire to consume the prey whole. Fifty years ago, Unovan children liked to “help” chandelure out by making a game out of attempting to get as close to one’s flames as possible without being burned, resulting in massive numbers of children being burned alive by this pokémon. The only thing that stopped these numbers from climbing any higher were newly enacted evolution stone control laws, put in place not because of the massive amounts of childhood deaths to pokémon that evolve by dusk stone but instead because the Unovan government realized exactly how much money they could make off state-controlled sales of evolution stones. There are groups in Unova who vehemently oppose such laws, less because of the state’s apparent disregard for children and more because of their personal right to own evolution stones, and if any of this sounds horrific, the writer would like to remind you that he’s speaking of the Unova region, so this should come as no surprise to anyone.
