The barbarian warlord known as Attuma was part of a sect of Homo mermanus, part of the Skarka Tribe that was exiled from the city of Atlantis some time ago, likely over their opposition of the royal ruling class. Prophecies spoke that a warrior would be born from the Skarka who would conquer Atlantis by force. Before Attuma was even born, his tribe was captured by the barbarian warrior Rorak. He had heard of the prophecy and sought to rule Atlantis by controlling the warrior's fate. Attuma was born during the battle, but his mother didn't survive. Attuma kept a clot of her blood from her heart. When Rorak saw this, he was so impressed that he spared the child's life. However, Attuma was put into slavery for years allong all women and children of his tribe. But while others grew weak and died, Atuma thrived working on the mines. The young Attuma soon grew strong, cunning and ruthless. Later as a youth, Attuma led his fellow Skarka to an uprising that slaughtered Rorak's minions while Rorak himself fled.
This group then settled in an area of the ocean referred to as the "Murky Depths". This society, too, prophesied that one of their own would one day overthrow the throne of Atlantis. From that moment on, Attuma was told by his people that he would be that person and since then he has lived by the sword. Through the years, Attuma grew to be the most powerful of his people, his ruthlessness cementing him as their leader. Atuma transformed the Skarka Tribe into an army of thousands from the Murky Depths, leading his tribe on a path of violent conquest.At some point in his adult life, Attuma sired a number of children. His first born was Andromeda with Lady Gelva, an Atlantean aristocrat allied with Attuma whom the warlord personally despised. Andromeda shamed Attuma for being female. Nonetheless, Attuma had the girl trained to be a warrior as though she were Attuma's son. Andromeda sought to prove herself by joining the Atlantean Army that opposed her father. The fate of his other children are unknown, however its possible they were estranged from their father in much the same way Andromeda was.
