De acordo com a Enciclopédia de Dunas , pode ter sido Sahkan
(10141-10228). Most generally described as Stilgar the Fremen or Stilgar the Naib, but in his youth as a wali in Umbu Sietch, known by his birth-name of Tuan. It was not until 10153, when he became a sandrider and accompanied a group of other youths on a raid against a Harkonnen village that he acquired the name by which he would be best known. (His troop name, used only by his comrades at Umbu Sietch, is thought to have been Sahkan — the Fremen name for a type of desert hawk — but verification of this point is difficult to obtain. The evidence found thus far consists of a reference made by a man from that sietch who accompanied Stilgar on jihad.)
Para registro, outro personagem cujo nome sietch é explicitamente confirmado (nos romances de Extended universe escritos pelo filho de Herbert) é Liet Kynes.
Dito isto, nenhuma boa explicação é fornecida por que esse nome seria usado fora do sietch por outros Fremen em Dune, nem por que eles o usariam na frente de pessoas de fora. Coloque isso em baixo para escrever mal.More than a thousand desert men uttered his sietch name over and over. “Liet! Liet!”
