Mygeeto

Mygeeto is a terrestrial planet in the Outer Rim Territories. Covered in vast expanses of natural crystalline structures, Mygeeto is the only source in the galaxy, outside of Ilum, of kyber crystals. The kyber crystals found on Mygeeto are less able to regulate the energy of a lightsaber than those found on Ilum.

Throughout the Clone Wars, Mygeeto was controlled by the Confederacy of Independent Systems. By 19 BBY, Winston Fridur was stationed on Mygeeto as a Commander in the Separatist Droid Army. In 19 BBY, the last of four Republic invasions was launched, led by Jedi Master Ki-Adi Mundi. After several weeks of fighting, Mundi was killed by his own clone troopers as part of the Great Jedi Purge. Shortly after, the Droid Army on the planet was shut down by a general shutdown order from Separatist Central Command. Less than a day after the shutdown, the majority of the Droid Army was reactivated by Winston, though its fighting was erratic and ineffective at halting the clone trooper advance.

Several weeks after Winston had reactivated the Droid Army, Newt Liryas and Thomas Verdi arrived on the planet in search of Jedi survivors and an explanation for how the Droid Army on the planet was still operational. Knowing that the defeat of the Droid Army was imminent, Winston escaped the planet with them soon after.
