Lynton Jellis
Lynton Jellis was a human historian who worked on Tysir IV in the 27th century. He was also a supporter of the United Poland Independence Party.
When the robot diggers on Tysir IV uncovered artificial materials during preparations for mining work north of Tysir IV's equator, Lynton successfully hacked into the systems of a Cyber-base which had accidentally been discovered by the robot miners, and learnt of both the base's nature and the Cyber-Plague stored within it. Hoping to acquire the Cyber-Plague and give it to the United Poland Independence Party so that they could forcefully win their campaign, Lynton lured Bernice Summerfield into a trap, recruiting her to assist him in opening the Cyber-base, whilst hiding his true intentions as to why; furthermore, Lynton also set up numerous explosives around the Cyber-base and sealed Bernice inside the base to ensure that she would die when his explosives detonated and destroyed the Cyber-base, with Bernice still trapped inside, while he escaped with the Cyber-Plague.
However, Lynton himself fell victim to a further trap devised by the Cybermen stored within the Cyber-base; unaware that the Cyber-Plague was spread through physical contact, he inadvertently infected himself by touching the outside of the vial which the virus was stored in, and as a result, he died in the lobby of the Cyber-base, just before the base's front doors. Bernice Summerfield and a sole Cyberman found his corpse only a few minutes later, and Bernice stole the deceased Lynton's gun to escape the Cyber-base while simultaneously trapping the Cybermen inside as Lynton's explosives detonated.
