A trusted aid of the Atreides, and champion of the Lady Jessica, Gurney is a most valued member of the great house.

Entrusted with the training of young Paul Atreides, and a close adviser to Duke Leto, Gurney Hallack enjoys the respect and loyalty of every member of house Attreidies. A skilled warier, he is as skilled in maiming with the knife and the shield, as he is with coaxing the sweet tunes from his favourite instrument the ballaset.
