Eris (Havoc)

Agent Eris was a Time Lord who served the Celestial Intervention Agency under Coordinator Romana and Deputy Coordinator Narvin during the early days of the Last Great Time War In the time shortly after Rassilon was resurrected to retake the mantle of Lord President of Gallifrey, Eris was the CIA's liaison with the War Council. (AUDIO: Havoc)

Investigating a murder
When Commander Jevon of the Chancellery Guard was murdered, Eris and Narvin reported the news to Romana. They examined the remains together, and Eris pointed out to his superiors where the Commander had been shot with a staser. Although he felt he needed to report the incident to the War Council, Romana ordered him not to and reminded him that, while he was the liaison to the War Council, he did not work for them. Later, when Romana encountered General Trave, who already knew about the shooting, she asked him if Eris had disobeyed her orders and told him about it. Trave claimed he already knew about it, and had simply asked Eris to confirm. He also told her that Eris was a good agent and that she should cut him more slack.

When Narvin discovered that the culprit had used a device that emitted anachron energy, with which they could be traced, he enlisted Eris in a mission to the former Matrix building in Zone Six to track the murderer. The two split up to search, at which point Narvin came across the culprit and chased after them. While Narvin ran after the person in pursuit, Eris could hear the struggle over his communication device. When Narvin fell and nearly plummeted ten stories, he was close enough to rescue him. Eris asked him why a man of his rank was doing this type of field work, which the Coordinator interpreted as suggesting that he was too old for it. Afterwards, they resolved to go and see the vote for the creation of a domestic security force. However, since the proceedings were quickly ended due to Lord President Rassilon invoking the Drylands Precedent and unilaterally creating the Interior Defence Unit, they did not get to see it.

After the vote, the traces of anachron energy dissipated, seemingly putting the investigation at a standstill. Although Eris reminded Narvin that Romana wanted to keep the investigation contained to the CIA, Narvin suggested they may need to turn to Lord Cardinal Mantus' Interior Defence Unit for assistance. During the call, recently demoted Castellan Bovari contacted Narvin and arranged a meeting at Pandak Square. When the Coordinator left for the meeting, Eris offered to serve as backup but he declined. Bovari showed Narvin a complete biodata record of the Citadel she had taken before leaving the Chancellery Guard headquarters, which could be used to track the killer. Eris, however, was concerned that using a stolen file that rightfully belonged to the IDU was a serious breach of protocol. Ursing the biodata records, they located the murderer at a recently constructed refugee detention centre by the TARDIS docks near Zone Six.

Eris moved to get his staser to arrest him, but Narvin order him to stay and was determined to make the arrest himself. Nonetheless, he kept in contact with Eris, who monitored the data to ensure the suspect did not move. Narvin confronted the man and killed him in the process, thinking he was reaching for his staser. Back at the CIA headquarters, Eris performed a gene scan on the body that determined the murderer was actually a future incarnation of Trave. Narvin then met with the Trave from their own time who still lived, and Mantus came to arrest him during the meeting. Narvin suspected Eris had told the IDU, a suspicion he relayed to Romana when he reported back to her, but Romana revealed that she had done it to protect the Agency from the same fate as the Chancellery Guard.

Mission to Ysalus
Later during the Time War, Eris was sent on a mission to the planet Ysalus with Narvin. Although Narvin did not want Eris to go, finding him to be too young and enthusiastic, Romana insisted he take him. En route to the planet, they listened to a message from her that explained the purpose of their mission. Though largely unknown to Time Lords at the present, Ysalus was in the midst of its first planetary war, between the Neo Solitairian and Ysalarian factions. According to Romana, if the Neo Solitairians won, the faction would shortly accede to a government dedicated to pacifism. If the Ysalarians won, however, the remaining Neo Solitairians would deploy weaponry that would leave Ysalus devoid of all life. Its fate was vital, due to its abundance of a natural resource needed in Dalek time machines. During the message, Eris attempted to take notes so that he could properly remember what was said, but was told off by Narvin for doing so.

The CIA plan was to pose as arms dealers and insert themselves into Neo Solitairian groups, in order to push the outcome of the conflict in the proper direction. When Eris and Narvin arrived on Ysalus, they landed outside a city that was at the centre of a crucial turning point in the war. If the city fell to the attacking Ysalarians, their faction would win, leading to death and destruction. Eris was displeased with their distance from their target, but Narvin did not want want to draw attention to themselves or their technology. Consequently, they were to swim into the city via the river. Before they could begin that journey, Commander Aladra of the War Council arrived, having found out about the CIA's plans. Narvin wanted to know her reasons for coming there, but she refused to reveal anything unless Eris returned to Gallifrey. Narvin agreed to the request, wanting to learn her motives, and Eris reluctantly left. (AUDIO: Partisans)

Personality
Eris was a young and enthusiastic Time Lord, both traits that Narvin, his direct superior, disliked. (AUDIO: Partisans) Eris had a strong sense of protocol, and thus felt uncomfortable with using the misbegotten Chancellery Guard biodate records. While loyal and largely obedient to his superiors, he was also struggled with loyalties to other factions, including the War Council to whom he was liaison and the more powerful Interior Defence Unit.

Eris was voiced by Samuel Gosrani in Havoc, Partisans and Collateral.
