Please forgive me if I'm doing this wrong, but I had a question and was directed here as a great source of knowledge. A group I play with is running something from Pathfinder--The Legacy of Fire--and part of it takes place in the City of Brass. I remembered from something I read the idea of "living brass" souls being infused into the structure of the city, but for the life of me I can't remember where I read this. I was hoping someone here could shed light on it, since it's driving me crazy.
It is mentioned in the fifth adventure, the city is build out of living brass harvested from souls. Necromancer Games version of the city also has the living brass.
