Crucible - the name of the world of A Signet Forever

I've been brainstorming possible names for the world in which this novel series takes place for the last 2 weeks. Today, I finally found a name I like - Crucible. I feel this name fits because, like a crucible, the world of ASF is a rugged container where the faith of its people are tested by intense heat. There's no escaping the rigor of it. It comes to those who prepare themselves for it and, alas, it comes to those who try to wish it away from themselves.
