On the Inferno Earth it was young Alistair who died in 1938, after accidentally falling down Golitha Falls. In that reality James never met Maha, and went on to become a major in the Coldstream Guards. In 1959 he met a man who he came to learn was his dead brother from a parallel future Earth, Colonel Alistair Gordon Lethbridge-Stewart. James travelled to a middle-reality in the 1940s with the colonel and there met another version of his brother, Alastair Lethbridge-Stewart. He was instrumental in saving Alastair, transporting him to the Inferno Earth where he met their father Gordon Lethbridge-Stewart, Director of External Security. (PROSE: The Schizoid Earth) James was greatly disturbed to see how his father raised Alastair to be the perfect fascist and last saw his 'brother' running a labour camp. (PROSE: Ashes of the Inferno)
At some point around 1969, James crossed realities, arriving on Alistair Gordon Lethbridge-Stewart's Earth in 1959. He brought his son, Dylan Lethbridge-Stewart, with him. James took the name James Gore (using the surname of his maternal grandmother), and changed Dylan's name to Simon. (PROSE: Night of the Intelligence) Also known as General Gore or simply the General, James became the head of the Vault. (PROSE: Mind of Stone) When he raised Simon he sheltered him from the outside world, believing it to be dangerous for him. (PROSE: Night of the Intelligence)
In January 1970, James and Alistair met. James intended this meeting to distract Alistair from the kidnapping of Owain Vine and Edward Travers. James planned to use Travers and Owain to tap into the interstitial void and travel to his own universe and save his wife. Instead he unleashed Sunyata, and it possessed his body. Due to the interactions of Padmasambhava and Owain in the astral plane, Sunyata's link to the universe was broken. James was relieved of his duties in the Vault and was replaced by Martyn Townsend of C19. (PROSE: Night of the Intelligence)
James moved his base of operations to the Red Fort in Norwich. When Gordon Conall Lethbridge-Stewart returned from the Realm of Light, James captured him. He interrogated Gordon about travel between worlds. (PROSE: The Man from Yesterday)
Alistair sent him a reproduction of a photo of himself and this universe's James as children; otherwise, the two had little contact and Alistair refused to let James meet his 'niece' Kate. (PROSE: Ashes of the Inferno)
In 1974, James Gore was living in an old age care home for retired officials from the shadier arms of government. While events occurred at the Inferno Project, James was haunted by memories and images of the Inferno Earth. Getting a vision of Brigade Leader Alastair Lethbridge-Stewart, James contacted Brigadier Lethbridge-Stewart, who informed him of Inferno Earth's fiery end and agreed to take him to the now-closed Inferno Project. While there, James saw a vision of Brigade Leader Lethbridge Stewart; when Section Leader Liz Shaw shot the Brigade Leader, the bullet also hit James. James died in Alistair's arms.
