Dweomer
In Dungeons & Dragons, a dweomer is an aura of magic; especially that which enchanted artifacts radiate. According to Wizards of the Coast, the word is pronounced either DWEH-mer (rhymes with "hem her"), DWIH-mer, or DWEE-mer.
Gary Gygax encountered the Middle English word dweomercræft in Susan Kelz Sperling's book Poplollies & Bellibones: A Celebration of Lost Words (1977), where it is defined as "the art of magic or juggling." Gygax invented such derivations as dweomered, dweomercræfter, and dweomercræfting.
