Ompuri Winwood has the official title of Operations Chief in Lord Chancellor C'jai's service. As he explains to Dillon in DILLON AND THE LEGEND OF THE GOLDEN BELL it covers a lot of territory as he is Lord C'jai's closest adviser and confidant as well as managing C'jai's day-to-day schedule and being in charge of his security. The position is hereditary as Winwood's family has served Lord C'jai's family for seven generations.
So who do I see as Ompuri Winwood? This rather popular chap:
Why Sam Neill? I really don't know. When I start writing these things I very rarely start off with an actor in mind as a template for a character's appearance or mannerisms. It was only after I finished writing the second draft that I started hearing Mr. Neill's voice coming out of Winwood's mouth and visualizing him as the character when I wrote the third draft. So there you are. Go figure.
