Page "Gurney Halleck" Paragraph 3

Halleck is Paul Atreides ' weapons teacher, as well as a skilled musician.

He is a chief officer of Duke Leto Atreides, and serves alongside Duncan Idaho as a Swordmaster of the Atreides Household.

According to Dune, Gurney was trained by " the best fighters in the universe ", and alongside Idaho and Thufir Hawat gave Duke Leto a war council almost unparalleled in the Imperium.

He manages to survive the fall of House Atreides on Arrakis with 73 men.

In the years after the attack, he falls in with the melange smugglers, eventually becoming a powerful figure.

His smugglers fall for a Fremen trap — a fake hoard of spice — and are almost killed before Paul, now the Fremen leader " Muad ' Dib ", recognizes him.

Halleck later becomes Jessica's loyal chief officer after nearly killing her, mistakenly believing she betrayed Duke Leto.

In the later novels it is implied that the two become lovers, although this is never confirmed.
