In 2258, shortly after his thirtieth birthday, he was sent to investigate a disturbance in Sector 14, the location where Babylon 4 disappeared. A tachyon pulse from the time affected spot caused his internal organs to age three times past his natural age. He managed to set the auto pilot to return to Babylon 5, and scratched "B4" into his seat buckle before dying from "natural causes." 
This unnamed Drazi met John Sheridan briefly during his imprisonment by Earth forces. When John refused to break under torture, this Drazi was ordered to provide an alibi for Sheridan. The purpose of this was to give Sheridan an out an encourage him to sign a confession. The Drazi expressed his fear uncertainty and Sheridan encouraged him to keep fighting. He promptly refused to cooperate and was carried out on a stretcher and electricuted or so it seemed. Later, after the captain continues to refuse to cooperate he is lead out apprently to his death. Then, he sees the executioner dressed in black who turns out to be the same Drazi before being put into another room with a different interrogator. It is unclear wethier or not this Drazi was part of the Earth regime or actually a resistance agent who arranged to save Sheridan.
In November, 2261 he was assigned to command Ground Station Alpha, a perimeter defence position for an Earthforce ground base on Mars. During the Battle of Mars his NCO assisted a resistance strike team lead by Number One and Michael Garibaldi in taking control of GS Alpha, shortly after he lost contact with GS Bravo.
An unnamed IPX Official contacted Maximilian Eilerson in June, 2267 to inquire about why he had not sent any topographical readouts, samples of alien technology, or anything that he had found while on the Excalibur. She demanded that he send along all the information he found on the next mission he went on. Max mulled over reporting the finding a colony of Dureena's race on Theta 49, but deleted the log before sending.
In 2257, as Babylon 5 neared its one year anniversary of going online, the Minbari Assassin was sent to the station with the intent to assassinate the incoming Vorlon ambassador, Kosh. He had been sent by his clan, the Wind Swords, to frame Jeffrey Sinclair for the murder, disrupting the new and still fragile peace of Babylon 5.
He was to meet Del Varner to buy a changeling net before arriving at the station but Varner was delayed. Instead he continued to travel on the Narn vessel and used a pod to burn through the station's hull. One aboard, he quickly tracked down Varner, killing him and using the net to assume his identity. The assassin was then able to take the form of Jeffrey Sinclair and poisoned the ambassador through a "patch" he applied to the Vorlon's hand.
When the station crew unearthed that someone had killed Varner and possessed the net, they were able to corner the assassin. Sinclair himself fought him, critically injuring him and proving his innocence at the same moment. Rather than surrender, the assassin activated a bomb on himself, after telling Sinclair that he had a "Hole in his mind." Sinclair managed to avoid the blast, with some help from Delenn, who apologized for the actions of the Wind Swords.
Panicked Man was a Babylon 4 worker trapped on the station when it disappeared in 2254 and reappeared in 2258.
When Babylon 4 reappeared, Sinclair, Garibaldi, and a handful of others boarded the station to investigate. When they entered the cargo bay the panicked man began firing shots at them and called them "monsters" and said, "I see you... you think I can't?"
He is stopped by Garibaldi, who flanked him while Sinclair was a distraction. They were quickly joined by MajorLewis Krantz who took the man into custody.
