Arthur Curry is a reluctant half-human, half-Atlantean warrior thrust into an epic underwater kingdom he never knew existed. When his estranged brother Orm threatens to unite the seven seas and wage war on the surface world, Arthur must embrace his destiny as the rightful king of Atlantis. Joined by the fierce and resourceful Mera, he embarks on a perilous quest across mythical underwater realms, battling monstrous creatures and ancient enemies. Torn between two worlds, Arthur discovers that his greatest power lies not in his superhuman abilities, but in his capacity to bridge the divide between land and sea. With the fate of both civilizations hanging in the balance, he must prove himself worthy of the crown—and the trident.
