Marlon Styx is a very confused spy. Originally assigned by the BIS to infiltrate the Isle of the Broken Key, he found himself swayed by the remaining predictions of Crystal Palace, including one which foretold his own "crosswise" allegiances. He is drawn between the two sides, and either a double or triple agent at this point.
He is a stern and pious looking bald man, suitable to be cast as a monk in an adaptation of The Name of the Rose.[1]
He managed to get into the masquerade party in "The Canvas of Dreams" and attached himself to Phrygian, whose presence and outfit was also foretold. At the time, he was wearing a peach cloak, a black turtleneck, bright red pants, and a red oval full-face mask. Austin took heavy inspiration from 1967 British TV miniseries The Prisoner for this, in particular the very similar outfit worn by Number Nine in the first episode of the series.[2]
