US Highway 1. A gray snake of concrete writhed past her. The Oceanrest exit let off onto an artery road, two lanes on either side of a double yellow line, a dying pulse bloodletting into the sea. Before the iron lung economy, there’d been a trailer park by the highway, and an ice cream shop, and a very large church. Their razed bodies curled in shallow graves, their bones hidden in underbrush. A monster licked the skulls empty, scavenged the flesh.

Deirdre had been born a witch. Mysticism resonated in her blood.

Although that didn’t make magic easy, it made it easier. For someone born without the natural aptitude, a ritual like this might take days. For her, it only took nine hours. Nine long, sweat-soaked, repetitive hours, during either the Full or New moon, using simple cantrips and complicated spellcraft to ensure a strong harvest of her esoteric flora.

We can sort fantasy realms into two general systems: one in which our real-world understanding of physics usually applies and therefore magic breaks those understandings and/or the fundamental laws of physics themselves; or another in which the fundamental laws of physics and the universe differ from our own enough to justify the existence and use of fantasy-world magic. While the former usually tends to be the more grotesque and horrific of the two, the latter retains the same basic source of fear: constant paranoiac uncertainty.
