The Magic Goes Away is a fantasy short story written by Larry Niven in 1976, and later expanded to a novella of the same name which was published in 1978. While these works were not the first in the "Magic Universe" or "Warlock" series, they marked a turning point after the 1973 oil crisis and Niven's subsequent transformation of the series into an allegory for a modern-day energy crisis. The setting was later used as a backdrop for the Golden Road series of novels The Burning City and Burning Tower, co-written with Jerry Pournelle, and the novel The Seascape Tattoo co-written with Steven Barnes.
