The Tholothian Defense Forces functioned as the planetary defense force for the Tholothian government, which was the ruling body on the planet Tholoth. In the time of the Clone Wars, the Tholothian Defense Forces were responsible for the creation of the heartwood blaster, a weapon that diffused the strained relationship between the Tholothians and their clone trooper comrades from the Galactic Republic, due to the clone troopers' tendency to quickly shoot anyone perceived as disobedient.
