History
Tut-Ak-Mun was the descendant of the Pharaoh Tut-Ak-Aten. Centuries ago, Tut-Ak-Aten foresaw an end to his empire and created a magic ring that could resurrect those of royal blood back from the grave if wielded by those who were of his family. Many years later in 1948, Tut-Ak-Mun joined up with an expedition into his ancestors' tomb. With an ancient scroll that told of the ring's location, power and weakness, Tut-Ak-Mun recovered the ring and used it to raise an army of the undead consisting the ancient Pharaohs entombed inside many of Egypt's pyramids. He then began pillaging the land in the hopes of taking over Egypt and ruling over its population with wealth and power.
The chaos prompted Namora to go to Egypt and attempt to stop Tut-Ak-Mun's conquest. She was no match for the mummies and knocked out. Before she could be slain, Tut-Ak-Mun spared Namora's life hoping to convince her to be his consort. Namora was brought to his palace where he told her his plans for conquest and she agreed to be his queen, secretly hoping to learn the mummies' weakness and stop them. Over the passing days, Namora earned Tut-Ak-Mun's trust enough for him to reveal that he waters of the Nile River had the power to stop his armies. On the day they were to invade Cairo, Namora convinced Tut to let her wear his ring as a final test of his trust of her.

Tut-Ak-Mun's army of mummies
Namora was given the ring and fled the Tut-Ak-Mun to warn the people of Cairo of the impending attack and assisted in the evacuation. When Tut-Ak-Mun and his mummies invaded Cairo, Namora battled the creatures, causing a massive waterspout to flood the mummies and send them back to death. With his plans for conquest destroyed, Tut-Ak-Mun dove into the Nile and apparently drowned himself, wishing to be with his ancestors.
Namora was last seen swimming off with the ring and presumably discarded it.[1]
