Lydus

Lydus is an elder Jiralhanae Chieftain who sued for peace with the Sangheili during the Reclamation conflict.

Peace talks
In March 2558, Lydus was one of the few Jiralhanae willing to discuss a peace treaty with the Arbiter, Thel 'Vadam. Lydus and 'Vadam agreed to discuss peace negotiations on the remote former Covenant planet of Ealen IV. The was assigned the mission of defending him and 'Vadam during negotiations. Before an agreement could be reached between both parties, they were attacked by extremists opposed to the treaty. Lydus immediately accused 'Vadam of betraying him, but quickly realized this was not the case. With the aid of his bodyguards and an escort team of Spartans, Lydus was evacuated from the processing center. However, a wing of hostile Banshees destroyed the evac shuttle, forcing the Spartans and the diplomats - Lydus included - to take refuge in a nearby parts depot.

While taking shelter in the depot, 'Vadam discovered a set of existing tunnels leading to an old fortified redoubt in which they could take refuge in. Before the Covenant forces could locate them, Lydus and the other diplomats escaped through the series of service tunnels, narrowly avoiding a Covenant Type-56 Lich. Jackknife then went ahead with the delegation's bodyguards to ensure that the redoubt was safe for the delegates to use as shelter. Lord Hood stopped to inspect a fallen Sangheili and discovered someone within the UNSC was leaking the Covenant information. Spartan Vladimir Scruggs radioed the others telling them it was safe to advance into the redoubt. However, unbeknownst to Lydus and the others, Scruggs had betrayed his fireteam, killing them and the delegate's bodyguards.

In the redoubt, Lydus continued to express his skepticism over whether the peace talk would succeed. Hood told him that the Jiralhanae would need Lydus as a leader if they were to survive. Scruggs suddenly appeared and held Hood at gunpoint, stating that he would reveal his demands once his associates arrived. Meanwhile, Captain Thomas Lasky informed the orbiting Sangheili and Jiralhanae ships of the predicament planetside. He attempted to convince them to send troops to aid the delegates against the Covenant, but the two sides refused to listen to him. Spartan Sarah Palmer was eventually able to kill Scruggs, allowing the group to move on. The ambassadors eventually managed to escape the planet aboard a Covenant cargo tug thanks to the sacrifices of Paul DeMarco and Fireteam Bailey, although the outcome of the negotiations themselves was left nebulous.

Personality and traits
Unlike most Jiralhanae, Lydus was reasonable and willing to make peace with the Sangheili and humans to aid his species. During the crisis, Lydus frequently expressed his doubts as to the capability and allegiances of the Sangheili and humans, often bickering with the Arbiter in particular. He originally blamed 'Vadam for the attack on the planet, but quickly realized that the forces were not allied with any of the delegates.

Lydus was quite intelligent. He realized that an alliance with the other species would aid the Jiralhanae, as their supplies and resources were diminishing. When the peace negotiations were interrupted, he was the one to suggest that the group should attempt to return to their ships, rather than wait for their ships to aid the delegates as it was possible the ships had been destroyed. Like most Jiralhanae, Lydus was very aggressive. He was furious when the negotiations were interrupted by Jul 'Mdama's Covenant faction and threatened to personally kill Spartan Scruggs when he learned that Scruggs had betrayed the delegates and had killed the bodyguards.

Trivia
In contrast to his subordinates, who are depicted in the likeness of the Brutes in Halo 3, Lydus has the flat-faced, tattooed design from Halo: Reach.
