Simon Laurent was a passenger aboard the Infinity Train. He was 18 years old and had been on the train since he was 10. His notable presence is established as the second-in-command of a former raider group: The Apex. He was one of the secondary antagonists of Book Two, and initially one of the co-protagonists of Book Three before gradually becoming its main antagonist and tragic villain. His number exponentially grew throughout Book Three, eventually becoming the highest value ever seen. Shortly afterwards, he was killed by a Gohm.
