My latest crystal harvest expedition has led me to M'haeli in the Expansion Region. I've never been there before and I almost did not return. After finding what I was looking for - a unique Nextor lightsaber crystal - I did not feel well. My med droid couldn't figure out what was wrong, so I did some research in historic books on my own. I found out that I got myself an ancient Sith wizardry flu and luckily I was able to mix an antidote.
Now that I've recovered, I can finally present you the next crystal: Nextor.
Used in a lightsaber the Nextor crystal creates a highly volatile, yet powerful blade. When you swing the saber, the crystal creates an almost instable sound to the blade, but when in idle mode, you can hear the raw power of the crystal.
