Talesian thermal detonators were a type of thermal detonators that were powerful enough to destroy a large building. Despite their great destructive power, they still fit nicely in a Human's palm. Usually, such weapons were only used by terrorists who valued the destruction of their enemies more than their own lives. Despite that, General Han Solo of the New Republic once brought one with him on Dathomir, in hopes of killing Mother Gethzerion and her coven of Nightsisters.
