Cupid Arrow

Cupid Arrows were the otherwise-harmless arrows used by the members of the Crew of the Copper-Colored Cupids to “romanticise” their targets using a magical “Love Potion” that filled them with a sense of universal platonic love. (PROSE: The Green Gorillas, The Winter Quests)

They originally created the Arrows themselves using wood bought in bulk, at a heavy discount, from a Prime Earth lumber mill whose owners had been romanticised for the purpose. Eventually, after the Mélange of the Mauve Muskrat briefly bought the factory and rocketed up the prices (causing the Great Arrow Crisis), the Cupids ended up taking direct ownership of the lumber mill themselves. (PROSE: The Mélange of the Mauve Muskrat)

By 1994, the Crew kept a supply of Arrows in their “emergency supply warehouse” on the Prime Earth, with a number being stolen by the Mob of the Maroon Magpie until the Cupids, in defeat, abandoned the emergency supply warehouse and moved its contents to another location unknown to the Magpies.

Cupid Arrows didn't work on Demesmaekerite-Dyed Discordias. (PROSE: The Drove of the Demesmaekerite-Dyed Discordias)

When Larrikin-1029 tried to romanticise Madame Tarsa during the Cupids' first direct encounter with her, she plucked the Arrow out of the air and analysed it, allowing her to begin developing an ersatz Love Potion. However, Larrikin, Pessimist-242 and Pessimist's Fog Ship subsequently destroyed her research before she could complete her first batch. (PROSE: The Toymaker's Labyrinth)

The arrows brought by Acquaintanceship-982 on his trip to one universe's version of the Land of Oz ended up gaining sentient life thanks to the Powder of Life, alongside his bow and his Fog Ship, all of whom took Ozma's offer to take up permanent residence in the Emerald Palace. As soon as it came to life, one of the Arrows displayed a reclusive and irritable personality, becoming known as the Disagreeable Arrow. (PROSE: The Crew of the Copper-Colored Cupids in Oz)

The hand on the single “clock” in Philatel-426's house (which just alternated between the work-time and sleep-time periods designated by the Department of Sleep) was styled to resemble a Cupid Arrow. (PROSE: A Copper-Colored Christmas Carol)
