Out of Milliways: there once was a note...

It's been a few years since... well, since something rather odd happened that no one quite seems to remember properly. Not outside of the proper circles, anyway.
For a week and a half, or perhaps two weeks, everyone who was anyone in Ankh-Morpork knew all about music with rocks in. One would think that sort of thing would be hard to forget.
Where was I when we lost power?
One, however, would be wrong; once the effects are negated, that sort of thing is almost too much for the typical human mind to keep up with. Even the young man who had been at the center of that little musical maelstrom forgot all about it and got on with his life.
He still doesn't understand why people ask whether he's elvish.

But music with rocks in will not be forgotten so easily.
Give me back my lack of reason
Tucked away in a corner of Unseen University's High Energy Magic building is a small wooden box, containing two crystal balls connected by a bit of wire. No one quite remembers what it's for, and the way the thing glows, no one really wants to find out. Not at the moment, not when there's more pressing research going on.
But an ant wandering away from the university's thinking engine has no such qualms about walking around the box, walking across the wire, making it vibrate. An ant wouldn't notice that the sound it's just set off is almost... otherworldly. Wild, even.

It knows its golden boy is still out there (despite its best efforts) and off his guard; there's a decent chance of captivating him again. More than decent, probably, once it figures out how.
It's time to try for a comeback.
Blow like tempest, my second wind...
