12-Uri

12-Uri was an explosive developped by the Ixians and was found by Bashar Burzmali to have been used by the attackers of the Bene Gesserit keep on Gammu. It was thought by Burzmali that the explosive may have been used to mislead the Bene Gesserit about the nature of the attackers, who Burzmali thought were in fact Tleilaxu.
