What If, Vol. 1

During a battle with Destiny, who was attempting to destroy Atlantis using his Helmet of Power, Namor the Sub-Mariner managed to defeat Destiny and he then swam to the bottom of the ocean, where he buried the Helmet of Power into the ground. While Namor was away, his cousin Byrrah manipulated the Emperor Thakorr into giving up his throne and using the signet ring given to him by Thakorr, Byrrah used his newfound regent status to imprison Princess Fen, the mother of Namor. Following the imprisonment, Byrrah struck a deal with Warlord Krang to give Krang power in exchange for his service, followed by a similar deal struck up with the High Priest Kormok of the Temple of Neptune. Later that evening, Byrrah spoke to the populace of Atlantis against Namor the Sub-Mariner, turning them against the Avenging Son.
