Zoph

Zoph was a distant planet located in the galaxy's Outer Rim Territories. Long before the Clone Wars, Jedi Padawans would travel to Zoph to seek a specific type of kyber crystal&mdash;the Zophis crystal. Such visits decreased in quantity once Ilum and its crystals grew in prominence. In the Clone Wars, the planet was held by the Confederacy of Independent Systems, the enemy of the Jedi Order.

Despite this, records remain of the crystals, which have a unique resonance made for unstable but devastating lightsabers. Such lightsabers can carve through durasteel with ease, but is vulnerable to fluctuations in power from the core.
