The Krm'sahn Crystal was a Sekotan grown crystal that was used primarily as the main crystal in Lightsabers, however only used by Templars of Twilight, due to them being the only ones with the knowledge of harvesting and using Sekotan Crystals in a Lightsaber. When used as the focusing crystal in a lightsaber, it gave the blade a dark crimson color, and it enhanced the use of force powers that one might consider "destructive" such as Force Lightning, Force Destruction and Bolt of Hatred.
