Brother vs. Brother
The Idylists - a group of pacifists living in self-exile from Atlantis - settled in the over 4,000 years ago. They knew no violence; Peace and serenity were their way of life. King Thar came into power and ruled from Shayeris, the Idylist capital city. Thar had inherited much of his ancestor's mythic power, and practiced sorcery alongside his brother, Slizzath.
The history of Atlantis is fraught with a recurring theme: brother against brother. King Thar was no exception. Thar's brother Slizzath thought the power should be his and resented his brother ‘taking' it from him. Slizzath was denied his birthright because he dabbled in the black arts (practicing necromancy – the evocation of the dead). He was banished from the but returned 20 years later with an army of undead soldiers. Thar assembled an armory of weapons, specifically designed to stop Slizzath.
The pacifist Idylists thought Thar was going insane. Thar's peace loving people revolted, killing their once-beloved king. Fearing the monarchy was tainted by foul violence, the Idylists banished his now-pregnant wife, Berra. Berra found her way to Atlantis and gave birth to a son - known she named Garth.
Before Thar died, he was able to use his magics to trap Slizzath in an other-dimensional prison. It was, however, an imperfect spell. Slizzath would be able to manipulate particular spells as a means of escape. Such a spell was Garth's birthright ritual spell he would perform to seal his mystical powers. Upon giving birth to Garth, Berra gazed upon his purple eyes, the Idylist mark of power. She knew he had the power and would one day evoke the birthright ritual spell, thus freeing Slizzath. Sadly, she left Garth to die
Berra was eventually welcomed back by the Idylists, and they kept themselves hidden from the rest of the sentient ocean-dwellers. Recurring attacks from Slizzath's undead army plagued the pacifist Idylists. This is what drove them into seclusion. Garth had long believed his mother to be dead.
Garth was found by Aquaman, who took the boy in. Garth became Aqualad, and began an illustrious career as an adventurer working with both Aquaman and the Teen Titans.
Years later, Garth was whisked away by Aquaman's father, Atlan, a mage who existed in another dimension. He told Garth his destiny was to become a powerful mage as well. Atlan trained Garth and taught him how to greatly augment his powers.
Upon his return, Garth encountered his uncle Slizzath, who had transformed himself using dark magic and became a demonic sea creature. Slizzath wanted to siphon Garth's mystical energies for his own dark purposes and free himself from imprisonment. Slizzath created a mystical a doppelganger of , who was created to dupe Garth. Garth saw through the plan and was able to defeat Slizzath, and once and for all maintain a sense of closure about 's death. It was at this time that Garth adopted a new identity as Tempest.
