[Star Wars] I'm a jedi and I've just lost my Lightsaber (and my right hand) How do I get another Kyber Crystal?

You would likely be chastised by the council as you've just lost you're only real possession, before being given permission to head to Ilum to collect a Kyber crystal.

The process of getting a crystal is simple enough, once on Ilum you'd meditate and use the force to find a crystal that calls out to you.

Basically the less stupid your reason for losing your lightsaber, the easier the whole process is.
