In the 21st century, the House of Conquest breaks the immortal treaties by attacking the House of Action. The Immortal Man, fearing his sister will succeed in killing him, initially plans to transmit his mind into a new recruit, a teenage boy named Caden Park who has the ability to read another's memories ("mind-swipes"). The plan fails and Immortal Man seemingly dies. Caden gains a "blood mask" device that the Immortal Man had developed before his death, and the computer mistakenly believes the teenager to be the Immortal Man reborn. With this, Caden can access Klarn's database and the memories of his dead followers. In retaliation for the House of Conquest's actions, and to prevent them from achieving victory, the Immortal Men disable the technology keeping their battle unseen, forcing the world and the Justice League to see evidence of the Eternal War.
