The crux of McAllen's plan is to place a corrupt Guardian in the Tower and use him to give McAllen control over both Stark and Arcadia. To this end he captured Gordon Halloway - a guardian-to-be - and subjected him to the Vanguard experimentation that split him in two. Gordon eventually became the head of McAllen's secret police, and effective second-in-command: McAllen even trusted him to capture Cortez on his own (with a "small army"). McAllen also uses his technology to facilitate the creation of Warrior Shifters, to hold Cortez prisoner and remove the Red Jewel that he holds.
