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
"Yn these landes, theye do ryde upone greate flowtinge beastes alike as those thate ye fyshermen do calle nawtilus; Ande these beastes, callede 'pyky-pyky' because of ye noises thate the beastes make, are troubelsome ande beastlye mountes, withe fowle temperes." -Telliamed ap Ynris, "Ye Westerne Landes".
(A levitating giant nautilus that makes a noise like "piki-piki" and is thus called a Great Piki-piki.)
