I had to choose something when I started Scorching and I was re-reading Dune for the xth time. Always thought Duncan Idaho was a kickass name for a character, but everyone on the web uses it.
Hayt was the first ghola of Duncan Idaho, made by the Bene Tleilax and trained in mentat skills and Zensunni philosophy.
While I am not that skilled in Zensunni philosophy and clearly lack any mentat skill, it is fun to know that the AVI I use is from the Spacing Guild, also from Dune, they originally bought the body of Duncan Idaho from the Sardaukars.
Of course, Judiciary Pag L.I.V.R. would have been a great nick as well, who knows, I might use it 😉
