You look for a firearm enchant in the Compendium, and you find one: "prykost". Furthermore, you read the preface on firearm enchants and realize that you've been using them wrong; you have to apply them in conjunction with a rune signifying "inside", so that it heats up the ammunition put into it only. A gun that burned anyone who touched it would be next to useless. This "inside" run is pronounced "nakarik" with a rising intonation on the second syllable.
You try out both of these runes on pieces of paper that you brought from the library, with mixed results.
You manage after a couple of tries to get prykost to "catch", so to speak, the rune glowing from the arcane energies affixed to it. The paper doesn't appear to do anything. However, you know by this point that one ought to exercise caution whenever dealing with these runes. Instead of touching it, you put your head to the floor and look along the surface of the paper. Sure enough, you can see some distortion of the light passing above it, indicating that the air is very hot. You quickly shuffle it with your foot into the corner, and leave it there.
The results of nakarik are much more easily apparent, and less dangerous. As soon as you finish the last stroke of the rune, and the magical energy starts to cause the inscribed character to glow, the paper crumples into a small ball. Curious, you attempt to pry open the ball, but only succeed in pinching your fingers. What had you just said about exercising caution?
