Garth returned to our dimension at nearly the same time he left, although he was approximately three years older upon his return. When Garth, alongside Atlan, returned to Shayeris, he found the city overtaken by undead creatures. Completely unaware of his own history or his uncle's powers of necromancy, Garth was ill-prepared for the sudden return of Aquagirl, risen from the grave. Together with Letifos (one of the shark warriors), Atlan, and Aquagirl, Garth descended into Shayeris. Just the sheer proximity to the ancient pool of ancestral magic allowed Garth to tap into the power, and charged with the purple energy, he recreated his costume out of the Idyllist red and black flag and renamed himself Tempest.
