Aquaman #21

In "null," Arthur finds himself stripped of his throne by the Council of Elders, who believe he’s too tied to the surface world. Banished and branded a traitor, he flees Atlantis only to discover the betrayal comes from someone he never expected.

In the wake of Corum Rath’s ascension as king of Atlantis, the underwater kingdom has severed all ties with the surface world. With Arthur presumed dead and Rath enforcing a brutal purge of those he deems unworthy, violence erupts in the Ninth Tride—where crime gangs prey on civilians and peaceful mutants alike. A shadowy figure emerges to challenge the chaos, while beneath the surface, Vulko schemes to undermine Rath’s rule and Tula offers quiet strength to a grieving Mera in Amnesty Bay. In the story "null," the fate of Atlantis hangs in the balance as secrets deepen and resistance stirs in silence.

In "null," Aquaman and Dolphin race through the depths, hunted by Drift soldiers carrying out Corum Rath’s brutal orders to eliminate all mutants. As Mera pushes her powers to the limit in a desperate bid to break through the Crown of Thorns surrounding Atlantis, Murk grills Vulko for secrets, while Dolphin guides Arthur to a hidden sanctuary for the persecuted. When Krush sends Kadaver to hunt them down, the hunter recognizes a ghost from the past—Arthur, thought to be dead, now among those he was sent to destroy.
