C. S. Friedman’s 1991 Black Sun Rising is the first volume of her Coldfire trilogy.
The Terrans who discovered Erna initially deferred settlement due to concerns about the planet’s seismic activity. Ultimately, the world was too promising not to colonize, a decision to which their descendants might well object. The incessant quakes are annoying … but they’re not the biggest problem. What is? The Fae.
The eldritch force called the Fae transforms human will into tangible consequence. The result is indistinguishable from magic. If that were not challenge enough, simple human expectations alter the world around them. Consequently, science and technology, reliable elsewhere, aren’t reliable on Erna.
Centuries after settlement, visionaries like Damien Vryce, priest of the Church of Human Unification, are still trying to come to terms with the implications of the Fae. Damien is not all work, however. He is courting Adept Ciani, which is why he is very upset when she is killed and her shop is levelled in a Fae-related mishap.
Matters are not as they seem. They are much worse.
