After a while the two have a child named Arthur Curry and things seem perfect, but when Atlantean soldiers find them, the princess agrees to marry the King to save the fisherman and their child. 30 years later a princess from another underwater kingdom named Mera visits Aurthur Curry and tells him of his heritage. Arthur explains he knows of his family and that he was taught by Vulko his mentor. Mera explains that his half-brother Orm has ruined Atlantis and Arthur needs to reclaim the thrown. At first Arthur says no but eventually they head off to stop Orm.
