Thompson is an ex-soldier, turned bodyguard, who appears to be based on [[The First World]]. Believing his squad mates to have died after he left the service, he encountered [[Higgins]], one of his ex-squadmates, which spurred him to begin investigating the lies told regarding their demise, and the mystery of their survival.
Thompson was employed by [[Ethan]], a rich and influential individual who offered to get Thompson back into the military if he so desired. It would appear [[Ethan]] was successful, in a way, as Thompson has since been reinstated was reactivated and issued with given new orders prior to entering a portal in the [[Portal hub facility]] on [[The First World]]. These orders later turned out to be fake, and Thompson was effectively exiled from [[The First World]] for deploymentasking difficult questions.
