Matt Horner
captain of the Hyperion
Matthew Horner was an idealistic Sons of Korhal recruit who became captain of the Hyperion and Jim Raynor's loyal first officer, serving as the conscience of Raynor's Raiders before rising to admiral of the reformed Terran Dominion fleet.
Matthew "Matt" D. Horner was a Terran Dominion admiral, captain of the Hyperion, and former member of Raynor's Raiders and the Sons of Korhal. An idealist who joined the rebellion to make a difference, he became Jim Raynor's loyal first officer and the conscience of the Raiders, fighting alongside Raynor and Crown Prince Valerian Mengsk to end the reign of Emperor Arcturus Mengsk and serving in defense of the reformed Terran Dominion through the End War.

An idealist enlists#
Horner came to the Sons of Korhal as a young idealist who wanted to make a difference and saw the Terran Confederacy as a tyranny worth fighting. By the time the Great War raged he was serving aboard the rebel ship Cormorant. (StarCraft II: Wings of Liberty; StarCraft II: Flashpoint)
The break with Mengsk#
During the Great War Horner worked alongside Arcturus Mengsk's newest recruit, Captain Jim Raynor, and quickly grew to admire him. He took part in the mission to Orna III alongside Raynor and the rebellion's second-in-command, Sarah Kerrigan, guiding them through the facility from the Cormorant. (StarCraft II: Flashpoint)
When Mengsk used psi-emitters to lure the zerg en masse to Tarsonis, destroying the Confederate capital and countless innocents, Horner was disgusted, seeing one tyrannical regime merely replaced by another. After Raynor broke from the Sons of Korhal, Horner went with him, and when the new Raynor's Raiders took Mengsk's flagship, the Hyperion, Horner came to run the ship and eventually became its captain. Two months later, over Char, he made a dangerous emergency warp jump on Raynor's order to escape the infested Kerrigan's zerg, returning months later to recover the surviving Raiders. (StarCraft; StarCraft: Queen of Blades; StarCraft II: Wings of Liberty)
Raynor's conscience#
Over the years that followed, as Raynor's doubts spread to the crew, Horner kept faith in his commander, trying to act as Raynor's conscience while keeping him focused and firing up the Raiders. It was during this period that he became the unwilling "husband" of the mercenary Mira Han, won as a prize in a poker game at Deadman's Port, a relationship he actively avoided thereafter. (StarCraft II: Wings of Liberty; StarCraft II: Flashpoint)
By the Second Great War, Horner still served as Raynor's first officer. He was distrustful of the convict Tychus Findlay, whom he caught accessing the Hyperion's archive without permission, and he continued to worry over Raynor's poor psychological state and drinking. He counseled his friend to let go of his guilt over Kerrigan, and his encouragement helped return Raynor to effective leadership. When the Raiders recovered evidence of Mengsk's hand in the fall of Tarsonis, Horner formed the plan to broadcast it across the Dominion, seizing the prototype walker Odin and using it to take the UNN Studios on Korhal. The resulting riots marked, for Horner, the true beginning of the revolution after years of frustration. (StarCraft II: Wings of Liberty)
Char and the road to Korhal#
Horner's faith in Raynor was sorely tested when the Raiders learned the Moebius Foundation was owned by Crown Prince Valerian Mengsk. He believed an assault on Char to deinfest Kerrigan was suicidal and the Dominion alliance unethical, and he feared the momentum against Mengsk would be lost, but he uneasily let his commander have his way. As the campaign progressed and Raynor put the belligerent Findlay in his place, Horner came to allow Valerian to prove himself rather than assume he was the same as his father. During the assault on Char he provided advice and support from the Hyperion, tracking drop pods and warning of incoming attacks until the Keystone deinfested Kerrigan. (StarCraft II: Wings of Liberty)
When Arcturus Mengsk's fleet arrived to claim Kerrigan, Horner devised the maneuver that lured the zerg onto the emperor's flagship and let the rebels escape, and he guided the running flight to Deadman's Port and Space Station Prometheus, taking a gauss round through the arm along the way. Through the rescue of Raynor from the prison ship Moros and the final invasion of Korhal, Horner collaborated with Valerian to evacuate as many civilians as possible while Raynor aided Kerrigan on the front lines, the battle ending with the death of Arcturus Mengsk. (StarCraft II: Flashpoint; StarCraft II: Heart of the Swarm)
Admiral of the reformed Dominion#
Now an admiral in the Dominion fleet, Horner fought through the End War, taking control of Sky Shield during the defense of Korhal against the Moebius Corps and, in the co-op missions, accepting Mira Han's mercenaries against Amon's forces. In 2508 he joined Raynor in descending into the Void to support Kerrigan and Hierarch Artanis against Amon. (StarCraft II: Legacy of the Void; StarCraft II Co-op Missions)
In the reformed Dominion he served Valerian Mengsk through the Defenders of Man insurgency, sheltering Nova Terra when she was branded a traitor and helping repel the Tal'darim Death Fleet at Vardona. By 2511 he remained admiral of the fleet, voicing caution when the Zerg Swarm under Overqueen Zagara sought aid on Gystt during the One-Day War, jury-rigging a psi-emitter and launching a nuclear strike on Valerian's order, an act he noted felt very much like something Arcturus Mengsk would do. A principled man who always weighed the morality of a choice and disliked drinking while on duty, Horner kept his ideals through every campaign he fought.
