That is actually exactly what I was looking for in regards to a reference. I think it's short hand for a reference of their location or something like that. Basically, I was trying to figure out when in the series the crystals showed up. And if they were in chapter 15 of book 2 (I assume you mean book 2, since he wasn't really in book 1 other than the bonus scenes), which is the last chapter of the book, I'd say it's a pretty good bet that this is something that is going to come up in book 3. Since we have yet to see Rourke in book 3 and Aleister only just showed up in the latest chapter, I'd say it hasn't come up yet, but will be soon. It may even have to do with Aleister's actions in the latest chapter.
