At the start of the Hero of Ages, Vin and Elend start to lay siege to Fadrex City. Their camp gets attacked by a small force while Yomen kills half their koloss with trebuchets. During that fight, Vin battle a mystery mistborn that she suspects is Yomen's. But I don't remeber Yomen having a mistborn later. Was that Yomen's mistborn or someone else? Do they show up again?
