Hes Glillto was the alias that Lai Nootka, a Duros arms dealer, used when he entered the Coruscant system prior to the liberation of the planet Coruscant. Like Nootka's other aliases, he created it by mixing and matching the first and last names of characters that appeared in a series of Durosian young-adult novels.
During the last days of the trial of Rogue Squadron pilot Tycho Celchu, Imperial Intelligence agent Kirtan Loor used the alias to make contact with Celchu's lawyer, Nawara Ven.
