Captain Lasky

Thomas Lasky served as Executive Officer aboard the UNSC Infinity under Captain Andrew Del Rio starting in 2552. Following Del Rio's removal after abandoning John-117 on Requiem, Lasky became the acting captain and played a key role in the battle against the Didact. Six months later, as Captain, Lasky led Infinity's assault on Requiem and showed exceptional leadership, keeping morale high and defending his crew during a Promethean attack. His ability to request assistance from Dr. Catherine Halsey further proved his commitment to the UNSC.

During the Covenant's assault on the Sol system in 2552, Lasky was groundside in Luna and performed heroic actions, including commandeering a Banshee to strike back against the enemy. By the end of the war, Lasky had risen to Commander and was appointed Executive Officer of Infinity. He played a critical role during a hijacking by Insurrectionists, where his quick thinking helped regain control of the ship.

Lasky continued to demonstrate his capabilities as a leader during the early 2553 deployment of Infinity to Sanghelios, and later in the search for the Halo rings. Infinity’s crash on Requiem brought Lasky into close coordination with John-117, whom he trusted completely, in contrast to Del Rio’s skepticism. When Del Rio refused to assist John in fighting the Didact, Lasky took decisive action, aiding the Spartan in his mission to defeat the Didact and prevent the Composer's use on Earth.

After Del Rio’s removal, Lasky became the official captain of Infinity and led the ship back to Requiem to clear it of enemy forces. Under his command, Infinity deployed Fireteams and launched a surprise attack against the Covenant, leading to the Second Battle of Requiem.

Personality Known for his renegade attitude as an "innie sympathizer," during his youth, Thomas was shunned universally by squad-mates and other classmates alike. Lasky was not hesitant whatsoever to express his views on the ongoing conflict with the colonies, even with the ardent stance on the conquering of the rebel effort by the majority of Corbulo Academy's staff and cadet corps. As a result, many believed that Thomas would not live up to the level of excellency set by his brother Cadmon, by then a marine junior officer in the Orbital Drop Shock Troopers, nor the expectations of his estranged mother. Few expected him to even graduate from the academy.

At the conclusion of his freshman year from 2525 to 2526, however, lingering doubts about his competency as a future officer were alleviated. Concern over his constant displays of pacifism and his sympathy towards the Insurrectionist cause fell aside as he successfully led his squad into combat using tactics that overwhelmed the enemy, causing them to peacefully capitulate.

Lasky also has a very high moral standard; when Admiral Osman ordered the execution of Catherine Halsey, he attempted to persuade Commander Sarah Palmer not to commit this action—showing his compassion for members of the UNSC as well as civilians whom he joined the UNSC to protect, not to kill

UNSC Infinity (INF-101) is an experimental Infinity-class supercarrier of the UNSC Navy commissioned following the end of the Human-Covenant War. Built in secret utilizing technology recovered from Forerunner and Covenant sources during the war, Infinity is the UNSC's largest and most advanced multi-role vessel to date. Infinity serves under the direction of Fleet Command.

Jul 'Mdama's Covenant, simply referred to as “the Covenant” by its followers, was a newly created splinter faction and terrorist organization formed from assets of the former Covenant Empire. Founded and led by Supreme Commander Jul 'Mdama, this faction continued to worship the Forerunners while also rejecting the Prophets for their betrayal, and opposed the Swords of Sanghelios following the end of the Human-Covenant War. It was later bolstered by the Didact's Prometheans and fought against the United Nations Space Command during the post-war era. Although the faction was generally recognized as a Sangheili attempted re-creation of the original Covenant and referred to as “the Covenant”, its members were identified as cultists by the UNSC and the organization itself was regarded as terrorists as opposed to an empire like the original Covenant. The Sangheili served as the faction's military leadership caste with total reign, free from the Prophets who had betrayed them in the original Covenant. The Unggoy served as cannon fodder. Likewise, the Kig-Yar were deployed as snipers and light infantry. The Mgalekgolo were deployed as super-heavy infantry. The faction also infrequently used Yanme'e infantry. Although a less formidable force than the original Covenant, this reorganized Covenant had amassed a considerable pool of military assets, though it had been observed that they "aren't outfitted like standard military."

The SPARTAN-IV Program is the fourth generation of the SPARTAN Program, consisting of members recruited from the United Nations Space Command Defense Force who were augmented to be capable of wearing a new variant of the MJOLNIR Powered Assault Armor (GEN2) armor.

Requiem, formally designated by its Forerunner creators as Shield World 0001, was a Forerunner shield world located in the Epoloch system. It once served as the central base of operations for the Prometheans, an elite class of Warrior-Servants, for thousands of years until the end of the Forerunner-Flood war. It remained sealed off for a hundred millennia since the end of the war, and became the site of major events as UNSC and Jul 'Mdama's Covenant forces stumbled upon it in 2557. The UNSC Infinity returned to Requiem in early 2558, resulting in a protracted battle between the UNSC and the occupying Promethean-Jul's Covenant alliance.

In the endgame of the Forerunner-Flood war, the Ur-Didact converted his Prometheans into machine-based intelligences, known as Knights, by using the Forerunner machine known as the Composer. These constructs, along with the Ur-Didact, survived the activation of the Halo Array, eventually awakening within Requiem and rising to oppose the UNSC in 2557.
