Some additional explanation on the effects of the contraceptives:

Although I refer to them as retrocausal, the unicorn horn doesn't directly change past events. Instead, it alters the current present to remove the effects of sex. In living creatures descended from the creature ingesting the unicorn horn, this has the effect of essentially removing half of their DNA (or a quarter, or an eighth, or etc… depending on the generation), turning them into very dead gooey blobs. But all the things those creatures did still happened. Presumably, if the offspring generations are far enough removed from the parent, they could potentially survive this, at least for a short time.

So essentially what happens when a termite queen gets hit by the insecticide, you end up with a lot of dead termites everywhere. (Now remember PL's recommendation that the insecticide not be widely used for agricultural purposes, due to the threat it poses to pollinators. Now remember that MCD is selling it for agricultural use anyways. Now remember that there's still debate over what the cause of colony collapse disorder is… Not saying that MCD killed the bees, but I'm not saying they didn't kill the bees either.)

I will also take the time to note that PL is willfully ignorant to what MCD is doing to procure the necessary unicorn horns, on a sort of "see no evil" philosophy (and this is why the genetic manipulation was done in-house by MCD, even though they used PL techniques to do it). PL is perfectly content to delude itself into believing that they're just making a better replacement for DDT, and as long as they continue to believe that, they don't have to worry about all that ethics stuff. (Reminder that PL, while definitely more ethical than MCD, is still a corporation driven by profit, and thus ambiguously neutral at best.)

Also, since I've already said so much, I'll just add that TAG is an acronym standing for Thaumaturgic Alteration of Genomes — basically a method of using thaumaturgy to produce controlled alterations in the genome of an organism. It will be getting some more thorough examination in a latter tale.

I wish I couldn't imagine exactly the kind of person who would want to use this.

At first I thought this is for people who want to preserve their virginity, but after reading this and checking the numbers, coupled with GreenWolf's recent explanation on the retrocausal part, holy shit.

Take your metaphorical +1s because I can't upvote more than once.
