Dr. Dassid Cree'Ar was the Duros alias of Nom Anor, the Yuuzhan Vong Intendant who had been responsible for much of the Yuuzhan Vong War. This alias was created by Nom Anor donning a gablith masquer, which allowed the Yuuzhan Vong wearer to assume certain nonhuman forms including Duros.
Officially to his comrades, Cree'Ar was a scientist working with the New Republic's Senate Select Committee for Refugees (SELCORE) terraforming operations on Duro to make it a haven for the countless displaced refugees. He was assigned to the main complex Gateway which was administrated by former Chief of State Leia Organa Solo.
Cree'Ar was responsible for producing plants and protozoans that began creating an arable zone. Despite this, he was unpopular among his colleagues since his operations had interrupted those of the other scientists. However, Nom Anor as Cree'Ar had been secretly sabotaging the operation including releasing naotebe winglings that destroyed New Republic refugee encampments.
