The name Ziggy is short for a mouthful of longer words - and Ziggy tends to be reserved in use of his own voice (with the notable exceptions of quietly narrating things to himself - or trash-talking significantly more loudly in battle).
He is a member of the Knights of the Black Sword out of Caer Dineval, joining with the Kalteswetteruntergrund in their efforts to end the Rime (which seem aligned with the aims of the Knights).
