I really think setting stuff like this is where the value's at, and rules are valuable only insofaras they enrich a setting. With that in mind, does your zine provide any rules that define the use or value of these "arcane crystals?"
Yes! I'll describe how they are used and how much they are valuable inside and outside the setting, so you can bring them over to your own campaigns. I don't have any specific mechanics in mind yet, but it will probably be something neutral like "x-in-6".
