When the Dominant Echelon required a more efficient method of creating sources of nuclear power, it was Vaar who suggested that instead of enslaving aliens to make them convert their planets to fuel, the Dominators could infiltrate alien societies and start a nuclear war.
Along with Navigator Deka and Probationer Azbo, Vaar came to Earth with 12 Quarks and established Dominex Industries under the alias "Dominic Vaar". Dominex came into a contract with the British government after demonstrating the benefits of negative mass flux absorbtion; the government would send their nuclear waste to Dominex and Dominex would convert it into energy. However, the nuclear waste was instead used to create nuclear missiles.
On the day that Vaar planned on firing the missiles at Russia, Alistair Gordon Lethbridge-Stewart stormed Dominex with the help of Ken Powell, Brian Hooper, and Jason Stevens. All of the Quarks and both of Vaar's colleague were killed during the siege, leaving Vaar to be taken prisoner.
Vaar was brought to a high-security prison, where he was to stay for the rest of his life. (PROSE: Mutually Assured Domination) Harold Chorley sought out Vaar, and was finally told that he needed to contact Sebastian Collins, who would lead him to Vaar. (PROSE: Moon Blink, The Dreamer's Lament)
In 1973, Vaar became involved in London's criminal underground.
