History
When Byrrah had assumed the throne of Atlantis and Namor had left in self-exile, Attuma saw this as an opportunity and attacked Atlantis. Within days, Attuma had destroyed Atlantis and killed Princess Fen, Namor's mother. When Namor finally returned, he killed Attuma's men and battled Attuma, killing him by impaling him on Neptune's trident.[1]
