Illiana

 is the wife of Ulog.

Background
Illiana was falsely imprisoned by Dayana Prucine.

Ulog stands before the Knights of Requital and airs his grievance about Illiana being imprisoned with hardly a trial, merely for being in the wrong place at the wrong time.

Ulog, with the Mighty Nein's help, found documents proving that Prucine knew Illiana to be innocent, but convicted her to make an example.
