Elias Haverson

Elias Haverson was a Lieutenant of the UNSC Office of Naval Intelligence.

Wreckage of Halo
Haverson was the ONI officer attached to the Pillar of Autumn. When that vessel crashed on Installation 04, Haverson was among those evacuated via lifeboats and managed to survive until the destruction of Alpha Halo, when he fled in a Pelican with Petty Officer Second Class Polaski, Staff Sergeant Avery J. Johnson, and Corporal Locklear. They hid in the debris field of the Halo until they made contact with Cortana and the Master Chief. As soon as they met on the Longsword.

Reach
The Pelican and Longsword were not capable of a Slipspace jump, so the group managed to capture the Covenant ship Ascendant Justice and Haverson gave tactical command to the Chief, despite his superior rank. Master Chief captured the ship by fighting hand on hand with a Special Operations Elite, injuring it and ejecting it in an escape pod. They then were forced to travel to Reach because of the Cole Protocol which prevented them from heading back into UNSC territory, especially Earth, that is not known by the Covenant, even with a captured Covenant ship.

Haverson journeyed with them to the surface of Reach, where the Chief collected the surviving Spartans and Doctor Halsey. After trying to flee the Covenant ships through slipspace, the crystal opened an alternate slipstream dimension instead, and Haverson and the others were forced to battle a small Covenant battle group within the strange dimension before dropping out near Eridanus Secundus. Haverson also accompanied Vice Admiral Whitcomb's team to the rebel-held asteroid-colony of Eridanus II to talk with Governor Jacob Jiles of the Eridanus Rebels, before they were forced to flee in the face of overwhelming Covenant forces.

Death
The Master Chief and his team of SPARTAN-II's then returned to the UNSC Gettysburg, after crippling the reactors of the Unyielding Hierophant. The Chief and his team then found out from Johnson that Haverson and Admiral Whitcomb took the wounded Flagship and waged a one-ship attack on the Covenant fleet gathered around Unyielding Hierophant, destroying a single Covenant carrier. This distracted the five hundred other ships, and they all converged on the to try and recover the Forerunner crystal used as bait - long-destroyed already, but imitated via hologram. The Unyielding Hierophant exploded, killing the Admiral and Haverson and destroyed over five hundred Covenant ships along with it. The sacrifice of Haverson and Whitcomb delayed the First Battle of Earth.
