As Aron Peacebringer provides protection, Leia Organa works to disarm an anti-matter bomb. Anti-matter bombs were a type of nuclear bomb that utilized anti-matter as their power source, and they were deployed by the Galactic Empire. These bombs possessed a very large blast radius and could emit a lethal amount of radiation, sufficient to produce a Cherenkov effect. Due to their immense destructive power, they could obliterate entire large cities with a single detonation, leaving vast swaths of land uninhabitable.
In the year 3 ABY, the Imperial General known as Sk'ar employed one of these bombs to completely destroy the Shivan city of K'avor. Later, he made an attempt to drop a second such bomb from a battleship with the intention of destroying Illyriaqüm. Nevertheless, Leia Organa managed to defuse this second bomb.
