A frigid world of crystallized ice, Mygeeto was a major holding of the InterGalactic Banking Clan that became a battle site during the Outer Rim Sieges of the Clone Wars. Mygeeto was between Ord Biniir and Morishim under control of the Confederacy of Independent Systems. The InterGalactic Banking Clan also constructed several cities in Mygeeto. These cities were used for administering the surrounding crystal mines, though they also contained vaults which were used by the Banking Clan to store its treasures. During the Clone Wars, Mygeeto became a valuable member of the Confederacy of Independent Systems and was as a result named by Supreme Chancellor Palpatine as part of a "triad of evil", alongside Felucia and Saleucami.
In the ancient trade language of the Muuns, Mygeeto means "gem." It's a fitting name for the glittering world, perennially locked in ice age and covered in crystallized glaciation. Its internal fires have long cooled, and the geologically dormant world has left a trove of precious stones within its crust and mantle. The enormous nova crystal deposits and fields of lasing crystals have made it one of the most valuable worlds in the galaxy. The Jedi had longed to explore the world for crystals suitable for lightsaber use, but since its discovery, Mygeeto had been firmly in the hold of the InterGalactic Banking Clan.
In the final phases of that extended campaign, Ki-Adi-Mundi was surprised to see his forces supplemented by a special 501st mission, dispatched specifically by Chancellor Palpatine. Though the Jedi general was wary of the circumstances, Bacara vouched for the unorthodox chain of command that saw the 501st ever mobile during the Outer Rim Sieges.
During a concentrated Republic push to rout the Separatists, Order 66 was enacted on Coruscant. Ki-Adi-Mundi was targeted by his clone forces, branded a traitor by the Chancellor of Republic. He was killed in a hail of blaster bolts.
During the Galactic Civil War, Mygeeto fell into the hands of the Rebel Alliance. Darth Vader then led a contingent of TIE Fighters to the planet to put down the uprising.
