*In a very excited tone of voice* My nephew Eb'ben has just made a very interesting discovery. I think he may have uncovered some information related to a 5th kind of crystal. Supposedly it holds an immense amount of power for the wielder to channel with. With such a power source, the tides of this war could be turned in our favor. I need you to go to Fira to speak with Scholom, the foreman of miners.
