I got this book, I believe from a crate in the first town:
The description says "Item", not Oddity or Artifact, and it's in my regular backpack, not the Quest Item section. I recently researched Oddities and found that most can be sold freely, while a few have subtle uses.
My question is, for an Item, how do I know if this can be sold without penalty, or if it has an application elsewhere? It has also crossed my mind that maybe this is what a Quest Item looks like before you pick up the quest? Maybe I'm wrong about that.
I am pretty new to the Numenera-verse, so I apologize if I am misunderstanding something fundamental about items or quests.
