Xbrr-Zinngogg was a Gran male diplomat from Rhommamool who later served as a loyal individual to the New Republic.
In 13 ABY, Xbrr-Zinngogg went to Coruscant in order to warn the New Republic Ruling Council about Nom Anor's attempts of destabilization in the Osarian system. Chief of State Leia Organa Solo refused to intervene, considering this situation as a local matter.
In Crimson Empire III: Empire Lost 1, "Rhommamool" was misspelled as "Rhommammoo".
