Before the Divinity convened the Council of Conjuration in 1725 and abolished magic, incanation, cantrip, and overt miracle from the world, many who had studied the arcane had chosen to impart some (or all) of their innate magickal energy into inanimate items. The most powerful of these were rounded up by the priests, ministers, imams, and other authorities who made up the Council. Items such as the Endless Soup Tureen of Tiruchirappalli, the Eviscerating Epee of Saint-Étienne, and the Cursed Calabash of Canton were confiscated and transubstantiated.
However, the Council’s bylaws explicitly allowed those artifacts not confiscated to continue in their function as long as their powers remained in a sort of grandfather clause. Reportedly the Purifying Pit of Pradesh, which cleaned the water used by an entire city, had persuaded a Councilman to press for this clause; the others, mindful of similar cases at home, agreed.
For many years, such grandfathered pre-Council artifacts were highly sought-after, and none moreso than the legendary Last Cantrip of Harry Culbertson. Culbertson, the legendarily lazy and laconic master of the last functioning magisterium school in Britain, had reportedly imbued a single object with the greater part of his formidable powers. He’d hidden it shortly before his death from hypergout in 1717 and many a treasure seeker had wasted a life in pursuit thereof. For what other than an artifact of immense power could have consumed the better part of the old arch-wizard?
That was the thinking, anyhow, until 2002 excavations near Cavendish Square to expand a parking garage unearthed a metal casket bearing Culbertson’s name and a magical seal. The seal was broken using modern magic (12 kg. of C4 from the Royal Engineers), and the legendary Last Cantrip of Harry Cavendish was revealed.
It turned out to be an indestructible pillow that retained its shape and fluffiness regardless of any external force. Apparently the legends regarding Culbertson’s love of leisure had undersold the matter a little bit.
