During the Outer Rim Sieges in the final months of the Clone Wars, Ki Adi-Mundi and his Clone Troopers were sent to the rainy, harsh world of Mygeeto to continue the Republic’s massive effort to push the separatists away from the Core worlds of the Galaxy.
While mediating during the battle, Ki-Adi Mundi experiences a heartbreaking flashback to when his fellow Jedi, Rivi-Anu threw herself in front of a Star Destroyer in hopes of using the force to stop it from killing both her Clone Trooper and Ki-Adi Mundi himself.
