Solari crystals represented an exceptionally scarce variety of kyber crystal. When integrated into a lightsaber, these crystals generated an unusually broad blade, enhancing its effectiveness in deflecting blaster fire. By the era of the Galactic Empire, their rarity led some to believe they were simply legends; typically, these crystals were acquired by individuals deeply connected to the light side of the Force. The resulting lightsabers were potent but required focus; a wielder's compromised connection to the Force due to internal strife would diminish the crystal's performance.
