Biography

Early life

Michael Bradley Horrigan was born in the city of Ganymede on Mars in 2527. He hailed from a prominent political family and his parents wished that he follow in their footsteps; instead, Horrigan was determined from a young age to pursue an action-oriented career, eventually ending up as a field operative in the Office of Naval Intelligence.

Terrorist attack on Sedra

On February 7th, 2556, Horrigan and his unit, led by Lieutenant Commander Jameson Locke were deployed to the Outer Colony of Sedra to investigate local terrorist activity, only to uncover a plot to unleash a bioweapon which specifically targeted humans. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying a Sangheili Zealot with a stasis refrigerant. While Gregory Ramos apprehended Axl, Horrigan, Locke, and Alistair Estrin pursued the Sangheili. Locke chased after the Sangheili into a city access tunnel, while Horrigan and the rest of the unit head directly to the city. Meanwhile, operatives Jordan Gaines and Mason Hundley attempt to implement lockdown protocols. Locke pursued the Zealot into a Sedran mall, where Horrigan arrived in time to watch the Sangheili jump off a ledge and activates the device, killing himself in the process. Many humans throughout the city began showing signs of infection, including Gaines and Hundley. The unit went to the Sedran Colonial Guard Hospital, where Horrigan and the uninfected members of his unit went through a decontamination process. After searching the tug used to transport the the element from the bioweapon used to infect humans to Sedra, the unit learned that the element originated from a fragment of Installation 04 in orbit around a red giant. The team discovered a second tug was travelling to the shard.

After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to uncover the origin of the bioweapon. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel travelled to the Alpha Shard.

Mission to Alpha Shard

Main article: Mission to Alpha Shard

After a journey through slipspace in the Condor, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, the Horrigan and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abaondoned tug used by the smugglers, Horrigan discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Horrigan and Locke quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared in large gestalt formations, the group retreated as three of the Sedrans and the horses were killed. The fast Lekgolo began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice.

Personality and traits

Michael Horrigan has been noted to be a compulsive individual. In contrast to his parents' wishes, Horrigan values the ability to rise up on the merits of his own strength and ability, not influence. In the long term, Horrigan views the Office of Naval Intelligence as humanity's best option for reconstruction and unity in the volatile post-Covenant War era galaxy. Horrigan is rather arrogant and over-confident, believing ONI to be superior to the Sedran Colonial Guard. He hyperbolically stated that the Sedrans were "two centuries behind" the UNSC and "still believe in Valhalla. Horrigan insisted that the mission to Alpha Shard was ONI's mission, which resulted in Sedran Colonel Randall Aiken ordering him to never repeat the sentence again and telling the rest of the mission's operatives to refrain from using the terms "ONI" or "Sedrans". Horrigan was very loyal to fellow operative Lieutenant Commander Jameson Locke, informing him that he would follow the orders of Locke over those of Aiken—who had taken tactical control of the mission to Alpha Shard. Horrigan enjoyed watching the explosion of HAVOK nukes in real-time.
