Artifact PSB: Psuedo-Scientific B*llsh*t. To put this another way: You have almost certainly come across the descriptions in the books such as how they made Royal Warstriders: In some of the dragon-blooded aspect books regarding study of artifacts or terminology... has anyone given any thought to a systematic IC system? that is - we look at the terms, assign meanings to them, create more glorious PSB, so that we end up with a consistent system for describing things.
Why? So that if your characters are researching a magic item, come across old manuals, or whatever, they could get the feel that it's a real system: that when it talks about ambient energy recovery systems (or whatever) it means the same thing it did three months ago... Also, why? Because some crazy minds might find it fun. :) Anyone got any ideas? - Molikai
