I just now thought of something: Even were humans to find some of this crystal, how could they even dream of destroying Zal-Ghombvis? Even the Dorlyans couldn't do it, and they had these weapons, plus they were like demigods of war!
A long time ago, I was writing a series of novels about the Empire of B'Gazzi and this Emperor thing. They were kind of like a combination of Dune and Tolkien.
It was like this:
1. The Emperor of B'Gazzi
2. Freedom Fighters of B'Gazzi
3. Shapeshifter of B'Gazzi
4. Death-Priests of B'Gazzi
5. The Fall of B'Gazzi Go to Comment
"Ladies and Gentlemen of Worth, please come closer and have a look... " In a little stand with numerous maps, the human Advantos sells land-rights with a shining smile and jovial talk at bargain prices. He sells even squatter rights (first to settle is the owner). About 20% of the lands do not exist or belong to someone else. About 30% do not have even that value, or have other problems attached- swampy, cursed, haunted, Old Indian/Pet Cemetery (tm)... Be assured you will not see this man in the same city twice.
