Three of my characters are close to lvl 7 and plan to enter the crystal cave on Mygeeto to harvest their own kyber crystal for their future weapons. This will be a standalone sidequest for them.
One of them is a scout with absolutely no force sensitivity. His goal is to build a weapon based on ligthsaber technology. He has no intention in becoming Force sensitive.
In my vision of the Star Wars universe one simply cannot power a weapon with a crystal without using the Force to build it, the item will explode. He has been warned in and out of character at several occasions.
But I'm really ensure how to deal with the cave part. It is supposed to give Force-induced vision to padawans to scare them or make them give up.
I don't remember any instance of non-force-sensitive in movies or the novels I read going into this kind of place.
I cannot forbid him to go as his character knows the location now. I do not want them to harvest many crystal to benefit from it (they are quite rare and worth a lot of money).
Should I let him take any crystal he find?
Should I not let him find any crystal?
Should I make the vision so strong his character will give up?
