Sir Landen Xavier

Tried to hire Thelonius to get his own yacht moved up in line for refitting at Windridge in the Forest system. Later, Thelonius foiled his plans to kidnap the adult daughter of Count Perry Tunstall (and allegedly shot her during the rescue). Xavier vows revenge against Thelonius Churchgate.

Many weeks later Xavier orchestrates the hijacking of the yacht belonging to the Marquis Franklin Kerry. The Yacht was taken to Ashmore, a small airless world in the Twins system. Churchgate and Kaito Saito were forced to drive for their lives while Xavier pursued them in a vehicle with his own driver. The two decided to hide in a cave on the asteroid surface were Xavier caught up with them and shot Kaito. While in the process of killing Thelonius, he was interrupted and shot by Roosevelt, a previous acquaintance of the two Travellers. Churchgate and Kaito assumed Xavier died in that airless cave.

Churchgate encounters a thug that had worked with Xavier on Ashmore. The thug was shot but spoke "Xavier ..." with his dying breath.

Churchgate and Kaito encounter an actor named Peter Johnson, who claimed to work for a man named simply "Sir X".

Thea encounters Xavier aboard the factory ship Grommet during an operation for the Mensah Water-Navy. Thea is drugged with a dangerous substance which could have easily killed her, luckily it just made her stronger (actually it made her a genius but technicalities). During this encounter a red haired girl was seen in Xavier's presence, she seemed to be his subordinate or partner.
