Zinethium was a substance that was both uncommon and lethal.
A chunk of zinethium In the year 13 ABY, a group of criminals raided the class-3 toxic weapons dump located on Nyara with the goal of acquiring a piece of zinethium. Although some members of the team died during the operation, the remaining individuals successfully fled the planet with the zinethium while being shot at.
The team's commander subsequently rendezvoused with Nom Anor on the world of Adumar and handed the zinethium piece over to him.
